Hi everyone! Good afternoon!
I have decided to start with the repair of my old Monroe OC-8820. I have tried information about it here (Trying to find a Monroe computers list) with a lot of interesting comments and good information. Thank guys!
Now, It’s my turn to do something with the machine. Sadly I couldn’t be able to get any manual/schematics/software of it, but I want to start with something basic while I’m still trying to find any helpful information.
My first step has been a complete disassembly of the unit. I have found a lot of dust, broke ics and several 4116 memories that seem that are bad. Them turn a bit hot, I will change them in the next step. Another ICs really suspicious are two 74LS283 (4 bits adder) that are really hot, so I will need to buy several new pieces before continuing with the repair.
a lot of memories to check:
I hope to have time to share my findings, any question or comments are welcome!
Also, if anyone has the same machine and need to check something with my unit, please let me know and I will try to help.
