EDITORS PREAMBLE
So here it is guys, December, in
case you had not noticed, and get
this, our next meeting .falls on
Friday Dec. the 13th.
No it is not an omen, Sinclair
wise that is, I don't know about
you personal.
Zeep,s back and he wrote a little
pome? Poom? Ah right, poem. It
started me thinking. How about
the great Sinclair limerick
contest, the winner gets to take
the Zeeper out for lunch at his
fave greasy spoon.
I'll start it of by ripping the
Zeep himself off, I mean I am a
computer tech right I don't worry
about the Zeeps little escapades
right?
Right.
There once was a hacker named
Darryl,
Who ignored the old Zeep at his
peril.
The Zeeper he thought,
is a bit of a fraud,
Until his smoking ZX showed his
error. :
Yes I know, it rambles, so send
me something better already.
Down to business.
The Nov. meeting was full of it,
business that is. It was decided
at the meeting, without any
serious objections, to raise the
yearly membership dues to $15.00.
So that’s what it is from now on,
15 smackers.
Wilf Rigter wondered whether it
would be possible to increase
services to the members along
with the dues. Wilf ofcourse has
been working on a memory bank
switching scheme and other
hardware clevernesses. Once he
has these things perfected he
will put ona little presentation
at one of the meetings.
downright oppressive.

Things like that are what
services to the members are all
about.
At the meeting Bob Denison and
Ken Abramson showed us the
intricacies of soldering while
the robot

services.
And let us not forget, writing
articles, or devilishly clever
SHORT little programs, for
publication in Your newsletter,
those are services too.
So "eh, when are You going to
start servicing.
John Brohman told us that the
Frog Hollow, Beach and Poco
bulletin boards can. be accessed
by 2X81,s with modems and that
these boards have ZX compatible
files on em for downloading.
Go to it guys and aside from
down, do some up loading as well
will you.
As mentioned Karl Brown was at
the meeting and he brought some
slide impressions with him from
the Pacific Robot show which he
attended. Over all he was not too
impressed with the hardware
displayed at the show especially
when one considers the “bang per
buck" ratio. In other words there
where some semi impressive pieces
of hardware to be seen but the
price of these things was
He is working on it.
With BERT.
BERT is the Basic Educational
Robot being built by the students
in Karl,s robotics class and he
was shown to us at the meeting.
Some of the student members
brought along there particular
versions of BERT and all in all
it seemed to me as if the BERTs
had a ball.

From Page 2
I have also mentioned before that
Ken A. and Bob D.put on a
soldering/desoldering show and it
was fun. Don’t ask me to repeat
here what was discussed it is too
much. It had to do with acid
cored tin/lead- alloy - soldering
wire and 200 watt soldering
irons.
The latter you apparently ought
not to employ on your ZX PC board
because it turns it all smelly
and black in no time flat.
Maybe I can talk Bob or Ken into
putting the highlight of their
presentation on paper.
Anybody else need some broad
hints? I got lots more where this
one came from.
Well that was pretty well it for
the meeting and as for me, I
think I’ll pack it up for this
issue.
See you at the meeting.

computers like the AMSTRAD which
are well susoorted anc delivered

I arrived in t^e nick of

management of the comoary so
badly that it was millions in
debt. Just like Timex hac David

his, a Ferranti chip secretly
implanted in his brain. He
thought that purchasing Sinclair

Let me 5811 you 5 ^ad ay

Maxweil had lots of money unlike
Higcenoottom who just had lots
of ideas. The oniy way i could
stop this demented man was to

it's the kiss of corsorate

sorry to say that you'il orobaly

PLAYING. WITH ELECTRICITY 8(x).. (Harvey Taylor)
Well I finally got. my printer . You will just. have to put up with
my messing around with different typestyles. Between Quill and the
LX80, there are a lot of different combinations to try.
In the-last column I managed to (fet. to Paul before the deadline
(sigh), 1 posted some results ofthe Sieve of Eratosthenes in Superbasic
and 68008 Assembler. Now that | have my printer, I can ret. the code on
paper & so bere it. is. Any of you who may be experienced 68K hackers
fay see ways to optimize the code. The 'CET FLP2 standard hdr3’ line at
the beginning is an instruction to the assembler to get the file which
contains all the QDOS system calls & values. ( Well most. anyway, I’m
adding them as ] use them & there are 1594 QDOS calls documented. )
By the way, that. reminds me. Anybody who 15 going to get into some
serious programming will find ADRIAN DICKENS “QL ADVANCED USERS QUIDE”
invaluable . There is also available from Boston Sinclair, The QI
Technical Guide , (0U2$20.00 + shipping) which has some additional
informat.ion.
Also by the way, If this article should happen to fall into tho
hands of any other QL owner, drop me 8 line. I'm trying to maintain
contact with as many Qi? ers as possible.
Back to the 11:211ከ(, as you see, most of the nonessential code
consist: of system calls (via QDOS, QDOS_N, VECTOR, &VECTOR N). This makes
it easy to do the simpie sorts of housekeeping things that always need
to be taken care of ...... BUT, IT MEANS YOU GOTTA DO IT THEIR WAY.
WHICH 15 OKAY IF 'THEY' HAPPEN TO BE GOING YOUR WAY, (EXCEPT HOW OFTEN
DOES THAT HAPPEN?)
THERE is a direct. correlation between the assembler listings and
the basic code of last time which will give you an idea
what the code is about, label by label. GET IN TOUCH WITH ME IF YOU

ODDS AND ENDS
A contributed by Arbie Fru
John Brohman bought a new printer and called me because he was having troubles
getting it to work with his Memotech Centronics. Seems his Old co-op's Epson
worked just fine but since he changed address he had to spring for his own and
it was not quite so co-operative. Anyway, this caused me to resume my search for
the answer to my (and nou-John's) printer problems. Via a tip from John the
search lead to Fred Nachbaur in Nelson and I might add the point to this story.
Fred and a couple of others are involved in a cross-continental publishing
venture called SuncWare Neus and a neu quarterly called MemoNotes. Fred was nice
enough to send a copy of each. SuncWare Neus is a good publication Catering to
the technical side. Lots of hardware and softuare projects and lots of digging
into the ROM to figure ways around ZX shortcomings. MemoNotes does basicly the
same thing for Memotext and Memocalc. Fred has several modified software
versions of Memotext one of which uses Powell Hargrave’s SDS fastloader Program
to really speed things up. MemoNotes costs US$13.95(four issues) and SuncWare
Notes costs US$19.95 (six issues) and both are available through the editor Tom
Bent 9016 Flicker Place, Colombia, MD 21045. f
So did all this solve John or my problem you ask? Don’t be naive it’s never
that simple in Sinclair land. John solved his problems by throwing money at
them. (he bought a different printer) I now know what the problem is and that it
can be fixed or gotten around and maybe someday.... I have been deliberately
vague as to what the problem is because explaining what happens would take up to
much space but suffice to Say that it has to do with the way the Centronics
handles linefeeds. If you are planning to buy a full size printer and use the
Memotech Centronics make sure the printer has a line feed command which can be
toggled to cause a linefeed + carriage return or to cause a linefeed only. Most
Printers have a toggle on the CR command, not all have it on the LF. This is
important because the Centronics only sends out LFs (apparently a nonstandard
thing to do). Unfortunately the cheaper machines seem to be the ones to leave
this toggle out.
THE ANSWER TO LIFE, THE UNIVERSE, AND EVERYTHING (8 K ROM)
Many people think computers are a black boxes with answers in them, and
that programing is a way of extracting answers from the computer. On the TV
series, Hitchhiker’s Guide to the Galaxy (a BBC production broadcast on PBS),
the second greatest computer of all time answers "the" question. It took
7.1/2 million years to run the program to completion.
.Fortunately, we had a monkey typing at random on our computer, and it
came up with a program which answers "the" question in only a few minutes. I
was frankly dísappointed with the result. But, anyway, here is the program:
1 LET A$="I-SQR IPEXP(-PI*I)/PI**2"
10 PRINT "ENTER YOUR AGE"
20 INPUT I
30 CLS
40 PRINT ,,,,"THE ANSWER TO LIFE,
THE UNIVERSE, AND EVERYTHING IS ";
42 LET I-VAL ልፅ (3 TO 4)
50 IF VAL A$ THEN GOTO 42
60 PRINT (STRS (VAL A$ (6 TO 12))(3 TO 4)
70 PRINT "ENTER A FRIENDS AGE"
80 COTO 20
The answer is, of course, a number. In case you do not believe that
there is a number which answers the mysteries of the Universe, I refer you to
Martin Gardner’s column in the November 1979 issue of Scientific American.
