Computer Concepts launch a new 
competition to find the best clip-art 
designed with ArtWorks. There are 
some excellent major prizes and 
hundreds of runner-up prizes. The 
winning entries may be published in 
a future clip-art collection. 

ColourCard 10 - 11 

More speed, more colours, 
and higher resolution 

The ColourCard is a revolutionary 
new Archimedes add-on card which 
allows you to have a much wider 
choice of screen modes. You can 
have more colours at higher 
resolutions, and the machine's speed 
is improved too. 

Computer Concepts 

No, not a new product, but great 
news nonetheless. Despite the 
recession we're pleased to be 
expanding our staff and working on 
even more new products and 
improved versions. (See our vacancy 
advert on page 5). 


Comment ! 

Kodak are carrying out extensive 
advertising of their new PhotoCD 
system. I'm not convinced that people 
will spend hundreds of pounds to be 
able to view their holiday snaps on 
TV. However I am convinced that 
PhotoCD could revolutionise colour 

For those of you who don't know, 
the PhotoCD system allows you to 
have traditional 35mm film scanned 
and stored on a special CD ROM. The 
amazing thing is that each CD can 
hold around 100 super high quality 
images, and that the service costs very 
little. A blank disc is just five pounds 
and each image costs about 50p. So 
for less than £20 you can get a 24 
exposure film developed, scanned 
and stored on a CD. With a suitable 
CD ROM reader and software you 
can read the images into a computer. 

Each image is stored at five differ- 
ent resolutions from 192x128 to 
3072x2048 pixels at 24-bits per pixel. 
This staggering resolution would 
require 18Mbytes of memory, and 
would allow the image to be typeset 
at very high quality at almost full A4 
page size. 

But there are two main problems. 
Firstly Kodak PhotoCD ROMs store 
the image in an encrypted format. In 
order to read the format each compu- 
ter manufacturer has to buy a. licence 
from Kodak, and code has to be 
licensed from Kodak to perform the 


actual reading. The other problem is 
that there is no support for 24-bit 
images yet under RISC OS, although 
this problem is actively being worked 
on by Acorn and software houses. 

Apple, IBM and Microsoft have 
all licensed the PhotoCD system from 
Kodak. In fact Apple are actively 
supporting the system by building the 
ability to read the PhotoCD discs into 
the operating system. All Mac appli- 
cations can have access to PhotoCD 
images, even if they don't support the 
format directly. 

For those who have seen our 
ColourCard in action you will pro- 
bably have seen some sample images. 
These have been obtained from 
PhotoCD and when shown in the 
ColourCard' s 32,000 colour screen 
modes they look astounding - full 
colour photographic quality. Unfor- __^ 

tunately to get the pictures onto the 
Archimedes we have had to go a very 
roundabout way: The images were 
read on a PC with PhotoCD reading 
software, saved in 24-bit TIFF format 
on the 1.44 MByte PC disc, read into 
an Archimedes and converted to a 
compatible format. 

Clearly we'd like to be able to 
read PhotoCD discs directly into an 
Archimedes. Lack of this could hold 
back the Archimedes from entering 
the low-cost colour revolution, so we 
must all hope that Acorn and Kodak 
can find a solution.

The Archimedean is issued free of charge to registered owners of 
Computer Concepts' Archimedes products. 


This issue of The Archimedean was created entirely in Impression 2, using 

an Archimedes 440 with 4MB RAM and a 20MB hard disc. All proofing and 

layout checks were output through LaserDirect. Final negative film was 

created from PostScript output files through a Linotronic 300 imagesetter. 

All colour separations were created with the aid of The Impression Business 

Supplement. Monochrome photographs were scanned using ScanLight 256 

or ScanLight Professional and placed in their required positions.

Acorn user show 
heads North 

The October London Acorn User 
Show was the best show we've ever 
been to. Now there is another being 
organised for the spring, and for the 
first time in years it's located north of 
London, in Harrogate (near Leeds). 

This exhibition is being presented 
by Safesell Exhibitions in association 
with Redwood Publishing (the pub- 
lishers of BBC Acorn User Magazine). 
It will be held over the easter period, 
April 15th-17th. 

Few details are available at this 
stage, but we expect to be there one 
way or another. Look out for further 
details which will no doubt appear in 
BBC Acorn User Magazine in the 
coming months. 

Hawk V9 mark II 

Wild Vision have released a new ver- 
sion of their popular Hawk full 
colour, real time digitiser. This ver- 
sion is now a single width podule and 
incorporates a programmable gate 
array (as used on the ColourCard, 
LaserDirect, etc). This is used to 
advantage to offer unique features 
such as hardware colour dithering for 
256 colour screen modes, which 
dramatically improves on-screen 
quality and, because the dithering is 
done in hardware, it's lightning fast. 
The board itself has a 16bpp frame 
store and so can also output super 
quality 16bpp true colour sprites (in 
the new Acorn 16bpp sprite format). 
The fastest and the best colour digit- 
iser available. 

Now available from Computer 
Concepts or Wild Vision for £269 + £6 
P&P + VAT (£323.12 inc). For further 
details please contact Wild Vision on 
091 519 1455. 

New ScanLight 256 
and software. 

It seems that innovation in scanner 
technology runs faster than ever. We 
are now supplying a new more 
advanced version of the ScanLight 
256 hand-held greyscale scanner. This 
latest model offers 100 to 400 dpi true 
grey-scale scanning, providing 256 
grey-levels for photographic quality 
results. This model is now faster and 
includes an audio buzzer to indicate 
overscan. The two tone buzzer indi- 
cates when you are scanning near, or 
over, the maximum scanning speed, 
which means you no longer have to 
keep an eye on the overscan light on 
the scanner. In addition the package 
includes a sliding scanner guide. This 
sits under the scanner and guides it in 
a perfectly straight line, making accu- 
rate scans a real breeze. 

The latest software, version 2.01, 
is quite an improvement over the 
earlier l.xx versions. For example the 
grey-map is now controlled by a 
curve in addition to simple brighness 
and contrast controls. The new soft- 
ware also provides easier control over 
image rotation and a large range of 
image enhancement options. 
Combine these with the existing Scan- 
Light software features such as 
instant image rotation by any angle, 
instant on-screen dithering for the 
best screen image, and you have the 
best scanning software there is. A 
recent Acorn User review voted this 
latest ScanLight software the best 
available (contrary to claims in a cer- 
tain other company's adverts !) So 
with the new faster scanner we feel 
this is the best hand-held scanning 
package you can connect to an 

For existing customers wishing to 
upgrade their existing ScanLight

New BJ200 Printer 
from Canon 


A brand new high resolution black & 
white printer has just been released 
by Canon, called the BJ200. This is a 
mid-range printer that is more expen- 
sive than the BJ10, but very much 
faster, and at about l/3rd the cost of a 
laser printer. 

At 360 dpi this printer can pro- 
duce near laser printer quality output. 
Indeed you have to examine a print 
very carefully indeed to distinguish it 
from a laser print. 

The Archimedes printer driver 
system expects to print pages as a 
graphic bit-map. This has the disad- 
vantage that the printer has to be able 
to print a full page of graphics 
quickly, but has the advantage that in 
so doing you can guarantee that what 
you see on screen will be reproduced 
exactly on the page. By printing the 
page graphically you are free to use 
any of the large range of outline fonts 
available, at any size. 

Computer Concepts will supply 
the BJ200 with TurboDrivers, a cable, 
a sample of top quality A4 paper (the 
printer will however print on any 
reasonable plain A4 paper), 12 outline 
fonts and the outline font manager. 
The total cost is £299+£10 Carriage + 
VAT (£100 less than the MRRP). 

The printer has a very small foot- 
print and so it occupies minimal desk 
space. It includes an A4 sheet feeder 
and built-in power supply. Neither is 
built into the BJlOe. 

The BJ200 prints a full page of 
graphics in about a minute - around 
three times faster than the BJlOe, and 
much faster than the DeskJet 500. 

The TurboDrivers are the fastest 
printer drivers available for the Archi- 
medes. With TurboDrivers' back- 
ground printing you can carry on 
using the computer while it prints. 

When printing pages of plain text 
the printer can manage around three 
pages a minute - nearly as fast as a 
laser printer. The speed of the 
TurboDrivers combined with the 
speed and quality of the BJ200 makes 
this printer the ideal desktop printer 
for Archimedes owners who can't 
justify the cost of a laser printer. 

In fact we are so confident about 
this printer that we will guarantee 
that this combination of TurboDrivers 
and printer is the fastest, highest 
quality printer available for under 
£800 - or your money back. 

Sample A4 prints are available 
free, on receipt of a stamped 
addressed envelope. 


ScanLight Professional 

Since the last Archimedean was pub- 
lished we have introduced a new 
model of our high quality flatbed 
grey-scale scanner, ScanLight Profes- 
sional. It's more compact, better 
quality, and cheaper too. 

The new model offers higher 
resolution grey-scale scanning and 
has had a dramatic price reduction - 
down from £899 to £595 +vat. The 
new model can scan at 600 dpi with 
256 grey-levels and an incredible 1200 
dpi at 16 grey-levels. It's also physi- 
cally smaller and lighter than the 
previous model (but can still scan a 
full A4 page). Since it can scan at 
such high resolutions we recommend 
its use with at least 4Mbytes of RAM, 
preferably 8Mbytes. 


The latest RISC OS 3 operating system 
(version 3.10) is now readily available 
from Acorn dealers (we cannot sup- 
ply). This upgrade is well worth 
getting - it offers numerous new fea- 
tures over RISC OS 2 and fixes some 
problems in RISC OS 3.0. While our 
software will work with RISC OS 2 
into the foreseeable future most, if not 
all, benefits from having RISC OS 3.1 
present. For example, outline font 
rendering is now much faster, and 
Paint, Draw and Edit are now in 
ROM, along with some outline fonts. 

The upgrade costs less than £50 
for RISC OS 2 owners (if you shop 
around). If you are an A5000 owner 
with RISC OS 3.0 then it costs only 
£15 so there should be no reason for 
not upgrading. (We can no longer 
support RISC OS 3 version 3.00)

RISC OS 3 Compliant 
Printer Drivers 

Contrary to certain speculation, all 
our printer drivers work with and are 
compatible with RISC OS 3. 
However, they don't take advantage 
of certain RISC OS 3.1 features such 
as rotated text. We have been work- 
ing on upgrading all our printer 
drivers to take advantage of these 
RISC OS 3 specific features, but this is 
taking rather longer than we antici- 
pated. When new versions are 
finished a free upgrade will be made 
available to all users who have 
already registered. In the meantime 
here are some points that may help. 

Warning from Impression 

If when you print you see the warn- 
ing from Impression saying you are 
using RISC OS 2 printer drivers on 
RISC OS 3 - DON'T PANIC. This is 
^p just a polite warning and not an error. 
You can still print perfectly. Impres- 
sion detects the RISC OS 2 printer 
driver and rotates images itself rather 
than relying on the printer driver. 

Printing rotated text 

Very few applications can rotate text - 
ArtWorks and the very latest !Draw 
are about the only things that can. To 
print rotated text from Draw, convert 
the text to paths first (it has a menu 
option for this). From ArtWorks you 
don't have to do anything as it will 
automatically detect RISC OS 2 
printer drivers and print text correctly 
anyway. If you export ArtWorks files 
to Draw files and they contain rotated 
text, make sure you have the 'Convert 
text to paths' option selected in the 
Choices dialogue before saving them. 

Homerton.Oblique not found 

If you see this error while printing it's 
because the QuickText printing rou- 
tines are trying to access the oblique 
^^ version of this font in ROM. This can 
be overcome in two ways. Either use 
disc versions of the Homerton font (as 
supplied with the original application 
discs) or turn the QuickText option 
off, as the error dialogue suggests. 

New Acorn machines 

The new A3010, A3020 and A4000 
computers are now available. These 
are far better than the previous A3000 
model - quite a lot faster, better screen 
modes, a 1.6 Mbyte floppy drive. 
However, in one respect they are 
poorer than the A3000 - they have less 
expansion capability. The only expan- 
sion available is one internal mini 
expansion board - there is no external 
expansion connector as on the orig- 
inal A3000. This means you can't 
connect a standard expansion board 
such as our LaserDirect to the outside. 

We are hoping to do a mini 
expansion board for LaserDirect for 
these new machines, but it's quite 
difficult to squeeze all the circuitry on 
the board. However we do sell a suit- 
able mini expansion card version of 
our ScanLight 256. 

The A3020 and A4000 have room 
for an internal hard disc, 4Mbytes of 
RAM and the one mini expansion 
slot. Combine this with Impression, 
ScanLight 256 and our new BJ200 
inkjet printer and you have a super, 
low cost, publishing system. 

No dongles 

One of the most common questions, 
from owners of the A4 portable com- 
puter in particular, is about the 
dongle on Impression and ArtWorks. 
So here is our official answer. 

We WILL be producing dongle-less 
versions of Impression II and Art- 
Works. As an alternative to the 
dongle we will produce a version that 
will run only on a specific computer, 
and will not require a dongle. This 
version can be freely copied for back- 
up purposes but will only run on the 
designated computer and no other. 

For those who want two copies of 
the program (and so keep the dongle) 
we will charge £60 incl. VAT for this 
second non-dongled version. For 
those who do not want a second copy 
they can return the dongle to us along 
with £10+ VAT and we will send a 
new customised version to them. 
Since we need to uniquely identify 
your computer the procedure is quite 
complicated. Firstly those interested 
need to contact us and obtain an 
appropriate form. Actually this is a 
program we supply on disc. When 
this runs it asks you for certain infor- 
mation and identifies your particular 
computer. This disc should then be 
returned to us, with the dongle if 
necessary, so we can create a per- 
sonalised version of the program to 
run only on your computer. 

This service is only available to 
registered customers who have an 
A5000,A4 Portable, A3010, A3020 or 
A4000 computer. This service will be 
offered from January 4th 1993 
onwards. If you are interested in 
obtaining non-dongle versions then 
please contact us after that date and 
we will handle the procedure. 




To be involved in the preparation 
of advertising and promotional 
literature. Experience with DTP 
software and layout techniques 
will be necessary, and marketing 
knowledge desirable. It is hoped 
such a person could also help in 
the preparation and production 
of this Archimedean magazine. 


In line with our continued 
expansion we are seeking addi- 
tional full-time programming 
staff to join the company. Ideally 
applicants will have an appropri- 
ate university degree in pro- 
gramming and have the ability to 
program in either high or low 
level languages (C or assembler).

Making a good 

With all the excitement leading up to the highly successful 
launch of ArtWorks, Impression may appear to have 
assumed a back-seat position, but development is actually 
continuing at even greater speed... 
Rob Pickering investigates the work underway. 


The Impression 
development group 

Mark Goodall heads the growing 
Impression development group at 
Computer Concepts and has some 
firm views about the future innova- 
tions he's working towards. He and 
his team of five programmers, soon to 
be six, are working on Impression 
2.18 and on the next major release, 
version 2.5. 

Since it's now been about six 
months since the last upgrade, I asked 
Mark Goodall to tell me about the 
current work underway on Impres- 
sion version 2.18. He explained "2.18 
has a few enhancements which look 
pretty minor on the surface, but have 
taken an incredible amount of work 
internally. Really what we've been 
doing is adding important support for 
ArtWorks. At the moment it's a bit 
tedious to use illustrations created in 
ArtWorks within Impression. You 
have to export them in !Draw format 
which is slow to display and print. 
Impression just doesn't understand 
how to interpret and draw ArtWorks 
files in Impression graphics frames. 

We've taken a piece of the Art- 
Works program and integrated it into 
Impression, so that it takes over the 
screen drawing and printing when an 
ArtWorks file is encountered. There 
was so much knowledge of ArtWorks 
required that we had to get Jim to 
work with us, and he wasn't available 
until ArtWorks was finished. (Jim - 
James Lynn, is one of the main pro- 
grammers and managers of the 
ArtWorks development group.) 

Another internal change we had 
to make was also, in a way, linked to 
the release of ArtWorks. The Art- 

Works package includes over 200 
outline fonts and some people have 
decided it's a good idea to install them 
all, and more besides! And who am I 
to argue? But when we created 
Impression we thought that a maxi- 
mum limit of 255 fonts installed in the 
machine was generous. Given that 
there were hardly any fonts for the 
Archimedes at that time, we could 
hardly imagine anyone having 255 
fonts, let alone installing them all. 
Impression doesn't crash or anything 
serious, it just doesn't let you choose 
from the full installed range. Conse- 
quently we've had to increase the 
number it can cope with. 

There are a few other little changes 
in 2.18 - an improvement in the way 
underlining is drawn, the ability to 
include foreign alphabet characters 
when spell-checking, and so forth. 

Before you ask, I'm not 100% cer- 
tain when 2.18 will be released, but it 
should definitely be by the end of 
December '92. There will be a small 
upgrade charge of £10+VAT to cover 
our costs, but that's all. Registered 
owners who ALSO have ArtWorks can 
quote their serial numbers and receive 
the upgrade free." 













While at Computer Concepts I think I 

may have found a clue as to why 
products take a long time to develop! 

What are the future 
plans for Impression? 

"We have a huge list of features we'd 
like to add to Impression, but we have 
to try and be realistic about what can 
be added in a given period of time. 
Ideally we'd like to release a version 
2.5 early in '93, with some of our more 
ambitious aims following later. That 
doesn't stop us from working on 
ambitious ideas, if they don't make the 
deadline they go forward to the next 
release. We've already been working 
for a few months on features for 2.5. 

I'd like to add a floating informa- 
tion bar like the one in ArtWorks. But 
there are internal reorganisations we 
have to implement relating to dialogue 
boxes before we can do that. We may -^ 
get some of this done for 2.5, but it 
would probably be asking too much to 
expect the information bar to be ready 
in time. However, I do intend to have 
a more flexible tabulation and for- 
matting ruler in version 2.5. 

Printing, especially the handling 
of colour, needs improving to stay at 
the leading edge of colour publishing 
in the Archimedes market. The first 
step will be to provide for manual 
selection of items to overprint. This 
seems to be the main thing our profes- 
sional users are asking for most often. 
In the long-term we need to be han- 
dling full colour continuous tone 
images, right down to colour separa- 
tion. Photo-CD is something that 
really interests us. As soon as it was 
publicly available we rushed out and 
had a film developed and put on CD. 
At the moment we have to use a PC to 
read the images! Displayed in 16-bit 
colour using our ColourCard the 
images look stunning. We want to be 
able to read images, import them into ^^ 
Impression, and either print in full 
colour directly or send colour separa- 
tions out through an imagesetter. This 
will really bring the Archimedes into 
colour publishing, but that's more 
than a couple of months away!" 



Automatic kerning 

Along with RISC OS 3 came an 
improved font format which can 
include automatic kerning pairs. 
Kerning pairs are specific spacing 
requirements for pairs of characters in 
a font. For example, if you position a 
letter 'A' next to a letter 'W the 
standard spacing will look too wide. 
Instead, the creators of a font can 
specify a smaller space to be used 
between this pair of characters, as 
demonstrated briefly in figure 1. 

Although Impression 2 supports 
manual kerning, it requires 
some knowledgeable 
intervention for each 
pair of characters that 
looks poor. So I wanted 
to know when automatic 
kerning would be sup- 
ported in Impression? 

Mark explained "It's always been 
our intention to support automatic 
kerning. We nearly added it to ver- 
sion 2.0, but Acorn assured us that 
they were creating a new standard- 
ised font format and that it would 
cause confusion if we created an alter 
native. As I understand it, EFF have 
been creating fonts with kerning 
information for quite some time and 
their file format has been adopted by 
Acorn as the basis for the standard. 

Now that the format is estab- 
lished and fonts with automatic 


kerning are available, there's nothing 
to stop us. I definitely expect to see 
this feature in version 2.5. Documents 
created with Impression will look 
better as a result, especially in large 
headline sizes where the problems are 
most apparent. 

The list of new features we want 
to put in Impression is endless. 
There's no problem thinking of new 
things to add - prioritising what we 
do first is the difficult part - aside 
from implementation of course!" 

/ wish 



Standard spacing with no kerning. 

Wren seen within the word 'drawing' 

the 'A' and 'W seem to be split. 


With kerning the characters look more 

evenly spaced and no visual break 

occurs in the word. 

Figure 1. Kerning 

The wish list 

The Impression Development Group 
keep a 'wish list' of the features they 
would like to add. It was only by 
looking down this extensive list and 
having some of them explained that I 
could understand why Impression 
development is a never-ending task. 

To conclude this look into 
Impression's future I decided to 
reproduce an extract from the wish- 
list. I've expanded on the descriptions 
in some instances where it seemed 
necessary. Any of these might appear 
in version 2.5, but not all. The rest will 
follow in future versions. I was asked 
to omit a few of the more unusual 
items from publication just in case it 
was read with more than a passing 
interest by any competitors out there! 

Impression Wish List

<j More Speed 
* More Colours 
Higher Resolution 



The Archimedes used to be 
noted for its colour graphics 
facilities, but by current 
standards it seems to be fall- 
ing behind... 

On a PC clone it's common to 
have resolutions of around 800x600 at 
256 colours, or even 1024x768 at 16 
colours. By comparison the Archi- 
medes only manages 640x512 at 256 
colours and 800x600 at 16 colours. 

The advantage of higher resolu- 
tion is that the image on the screen 
looks cleaner, crisper, and text is 
easier to read at much smaller sizes. 
Ideally it should be possible to read 
small text with ease, while showing a 
full page without scrolling. 

For users of Artworks or any 
drawing program it's easy to under- 
stand the advantages of more colours 
on the screen. At present it's neces- 
sary to work at a rather poor resolu- 
tion in order to have 256 colours on- 
screen, which means you can't see 
much of the page. Having more 
colours and more resolution would be 
ideal. Even for users of monochrome 
screens there are problems. Whether 
you have colour or monochrome, it 
isn't possible to show accurate greys- 
cales for scanned photographs. 

Unfortunately the existing Archi- 
medes hardware alone can't provide 
anything better than it already does. 
Even now, the machine runs very 
slowly in high screen modes, so even 
assuming that better modes were 
available, everything would grind to 
a halt. Add-on cards to address these 
problems have only been discussed as 
a possibility, until now... 

Cue The ColourCard... 

ColourCard has been designed to 
address the need for higher resolu- 

tions, more colours and to ease the 
speed problem. What it offers can be 
summarised as: 

• Higher resolutions 

• More colours on-screen 

• Accurate grey-scales 

• Increased speed 

• Reduced screen flicker 

• Compatibility with current software 

The ColourCard was developed as a 
joint venture between Computer 
Concepts and Wild Vision. It is a con- 
ventional half-width expansion board 
which is suitable for A300*, A400*, ' 
A540 and A5000 series machines. It is 
easily fitted by experienced users in a 
few minutes, (no soldering). 

To better understand what the 
ColourCard offers and the way it 
appears in operation, each of the fea- 
tures is described below in detail. 

Higher resolutions 

The card offers a selection of new 
screen modes at resolutions up to 
1152 by 848 in 16 colours. Many other 
modes are available, all completely 
compatible with existing desktop 
software. A summary of some modes 
is shown in Table 1 . 

Higher resolutions give more 
detailed, higher quality screen dis- 
plays. Particularly suitable for 
graphics and DTP work, these higher 
resolutions now also make 17" or 
even 20" monitors both practical and 
extremely effective. 

More colours 

The ColourCard supports a 24-bit 
fully programmable palette. This 
means that in 16 and 256 colour 
modes all colours are selectable from 
16 million possible hues. Also a new 
256 colour palette allows ArtWorks to 
offer improved screen dithering. 
Finally, the board supports medium 
resolution 15 bits per pixel, true 

The new maximum mode contains a pixel area three times larger 
than the standard VGA mode 27 


colour, screen modes offering 32,000 
colours on screen at once. These 15- 
bit modes are ideal for showing full- 
colour photographs, can be accessed 
specifically by BASIC programs, and 
a version of Artworks that will oper- 
ate in the new modes is shortly to be 
released. However, the 32000 colour 
modes are not yet compatible with 
the desktop, but we and Acorn are 
working on it.

An alternative greyscale palette offer- 
ing true 256 grey levels has been 
provided for accurate greyscale work. 
This is ideal for applications involv- 
ing scanned black and white 

Increased speed 

The ColourCard uses an off-board 
video frame store so that the main 
Archimedes processor slowed down 
by continual memory access from the 
video controller. This means that the 
speed penalty for running higher 
resolution screen modes is a thing of 
the past. 

Reduced screen flicker 

The ColourCard can display the pic- 
ture at 60Hz or more at all resolu- 
tions; in some cases, such as 1024x768, 
\ at over 70Hz. This completely elimi- 
* nates visible screen flicker, producing 
a steady and restful display. 

Full compatibility 

The ColourCard is completely com- 
patible with existing software. All 

correctly written desktop software 
can take advantage of the new screen 
modes possible. The ColourCard also 
offers the unquw ability to pass 
Acorn video modes through the card. 
The video pass-through means that 
all existing Acorn modes are not 
affected at all - and so even those 
programs that access the Acorn VIDC 
video controller will still work. With- 
out the video pass-through you 
would have to disconnect the monitor 
from the ColourCard and re-connect 
to the Archimedes to run such 

For the technically 

The ColourCard contains 512K of 
dual ported video memory on board. 
This is indirectly mapped into the 
conventional Acorn video memory - 
this is one way it guarantees compat- 
ibility - programs and the operating 
system can write to the Acorn video 
memory as normal. 

An Inmos video controller then 
re-displays the image from the 
ColourCard frame store and also 
contains the 24-bit fully program- 
mable palette and hardware cursor 
that replaces the Acorn hardware 
cursor. The Inmos controller can 
support a variety of different screen 
depths including the common 16 and 
256 colours modes but also 15 bits- 
per-pixel modes where each screen 
pixel is made from 15 bits of memory 
- five bits for each primary colour red, 
green and blue. This means that each 
pixel can be set to any one of over 
32,000 colours. 

The card also uses a program- 
mable gate array (as we use on the 
ScanLight and LaserDirect boards) 
that allows us to change the circuit 
design purely under software control. 
Given the differences we found in the 
timing of the Acorn video circuitry on 
different machines we found it neces- 
sary to be able to adapt the circuit to 
suit different machines - this is the 
only way we could get a single design 
to be fully compatible with all 

Free utilities 

! Clearly is a utility which allows 24- 
bit images to be previewed in the 

32,000 colour screen modes. It loads 
ClearFile format images and dithers a 
24 bit image so the 15 bit modes will 
produce pictures that are indistin- 
guishable from a true 24-bit display. 
A high quality sample image is 
included with the package. This is the 
utility we've been using to display 
Photo-CD images after conversion. 
FlipTop is a simple screen mode 
changing utility. With the prolifera- 
tion of screen modes it is becoming 
increasingly difficult to remember 
and keep track of the different mode 
numbers. FlipTop shows the modes 
graphically in a window - you can 
select a new mode simply by clicking 
on the point on the grid. It also makes 
it very easy to switch up and down 
the number of colours while main- 
taining the same resolution.

Computer Concepts Expands 
Despite the Recession 

At a time when many com- 
panies throughout the UK are 
considering mere survival 
and many are shedding jobs, 
Computer Concepts is still 

Charles Moir, Managing Director 
of Computer Concepts commented 
that "Turnover and profits are up 
considerably on this time last year, 
and it's a steadily increasing trend. It 
would appear that while companies 
are unwilling to make major capital 
investments they show no such reluc- 
tance in buying software. However, 
most of the market strength is pro- 
bably with the spending power of 
home and educational users. The 
Acorn User Show was a clear signal 
that there was no shortage of cus- 
tomers willing to purchase." 

The home of Computer Concepts 
is Gaddesden Place, a large country 
house in rural Hertfordshire. The 
house, built in 1768, was the first to be 
designed by the famous James Wyatt. 
In the past few decades it saw steady 
decay until purchased for Computer 
Concepts as the new headquarters in 
1984. With planning permission 
granted, restoration of the house and 
sympathetic integration of offices in 
the basement began and has never 
completely ceased. 

With the successes of Archimedes 
products has come the necessary 
funding to start the next major stage 
of restoration. The house originally 
had two large wings, each of about 
9,000sqft, but these were demolished 
when dry rot took hold about 40 
years ago. Early in 1992 work started 

on the ground floor development of 
one wing, designed such that the next 
floors can be added at a later stage. 
When complete, it will be as similar 
as possible to the original 1768 design. 

The 3,000sqft ground floor wing 
was completed and occupied in 
November 1992, providing a more 
suitable packing and delivery area. 
"We used to have to carry everything 
up and down a flight of stairs" said 
Mr Moir. "You can imagine how 
popular we were with the couriers 
when we started selling laser printers 
- if you've ever felt the weight of one 
you'll know what I mean. Now we 
just load and unload at the entrance 
to the new wing." 

The additional offices in the new 
wing have made room for new pro- 
gramming staff, and several new 
people have joined the team. "We 
used to be limited by the available 

space" said Charles. "Now we've been 
able to take on a significant number of 
new people, and we're still looking 
for others." 

Finding good programmers has 
always been a difficult and time-con- 
suming task. Once potential 
employees see the surroundings they 
soon warm to the prospect, as Charles 
explains. "There aren't many places a 
programmer can work where there's 
a heated indoor pool, a tennis court, 
full-size snooker table, and excellent 
offices set in pleasant countryside. 
Staff can use the facilities anytime 
during the week. The annual tennis 
tournament is great fun and a wel- 
come break from staring at computer 
screens all day." 

With the sales of ArtWorks really 
taking off, and equally interesting 
products already under development, 
the future for Computer Concepts 
looks particularly bright.
