Found the forum whilst serching for details of in circuit ic testers - thought you see an interesting bunch!
Now retired, I've spent a lifetime supporting industrial process control computers, and I like to keep my hand in.
My current 'project' is a 1984 Micon 850 CNC lathe controller, based on an 8085 micro but now dead. No circuits, no obvious clues, and I'm 'knife and forking' my way through it. Nine rack mounted circuit boards, mainly LS TTL, about 30 to the card. I have a vague idea of the fault area, split between two boards. So far I've managed to ring out one card manually and plot the circuit in Protel Explorer DXP (four days work and now cross-eyed!), and am starting on the second. Slight delay as I'm having to define some of the ics on it in Protel. (It doesn't know an MM5035 Octal 80 bit shift register, and suprisingly nor does it know an MM2102 1K static ram chip.
Hey - anyone know anyone who worked at Micon in Basingstoke in the mid 1980's ?????
