I am a collector of old bits of equipment, with special interest in the 6502. I started programming on an LJ electronics EMMA board. I have aquired an LJ Electronics SA3 Logic Analyzer but not the manual. I have got part of it to work, in that I can capture data and see it on the LCD screen and on an attached Oscilloscope.

It states on the screen that it supports disassembly of 6502, 65c02 and Z80.

Anybody got a manual or some idea of the correct 6502 signals to connect to each input line?

Did you get anywhere with this query?

There's one of these on ebay at present for $125 but no mention of manuals. Maybe someone here will pick it up and reverse-engineer the ROM...



Note also this other thread, about an LJ Electronics Emma 2 (or EmmaII) Educational Microcomputer System board, which has turned up a manual (for that device). I don't see any SA3 manual nearby though.

Thanks for that, working at present on getting my logic analyzer working. It is a CLAS4000 which has a Apple Mac as its brains. When I have time I will disassemble the SA3 again and copy the roms.

A ROM dump would be interesting!
Cheers
