ROM dumps for the Fluke 9010A Microsystem Troubleshooter. These ROMs were 23128 PROMs, but you could use 27128 (16kx8) EPROMs to replace them since they are pin-compatible. I did measure the access time at about 140ns, so you might need to take that into consideration. This is likely a minimum, and I know the absolute maximum is 750ns, so practically somewhere in between is what you need. Anyway, there were three ROMs, and the version given by the display was 2C. I have marked the locations of...

ROMs for the HP4140B pA Meter / DC Voltage Source. Each ROM was a Fujitsu MB8516, which is pin-compatible with any 2716 (2kx8) EPROM. All ROM dumps are in both BIN and HEX formats, so you can choose whichever is most convenient for your EPROM programmer.

These are the EPROMs for the Gould PG-4064 Digital Pattern Generator. When I got mine, only one of the stickers was still in place, and that only barely. All the others were in the bottom of the case due to dried out glue, so I don't know which label is which. In any case, I have marked the locations of the EPROMs on the image. U32 is a AMD AM2764DC. U32 and U38 are Fujistu MBM27128-25. U43 and U50 are NEC D27256D. I've given you both the BIN and Intel HEX formats, so you can choose either one...

Dump of the HP 4145A Semiconductor Parameter Analyzer ROMs. There are five, and I've uploaded them in both Intel HEX format, and plain old binary format. Either is suitable for an EPROM programmer. Four EPROMs are from the main CPU board (board A2), and were Fujitsu MBM2732A-35 4kx8. All had datecode 8338 (38th week of 1983). One EPROM (rom_04145-85068) is from the SMU controller board (board A3), and was a Fujitsu MBM27C128-20 16kx8. Note that there are two versions of this board, a later...
