Just to give you an update. After I had nicely soldered new LEDs into the #Imsai8080 clone front panel, it completely stopped working yesterday. So I took advantage of today, Sunday, to desolder all the TTL ICs and replace them with sockets. And you won't believe what I found there. Someone had already tried to repair something there before me. This was evident from the fact that IC 2 was a 74LS type, unlike all the others without LS. And a socket was soldered in for IC 14. In the pictures you can see what was hidden underneath. I think the cut between pin 4 and pin 11 looks intentional, though. But not the missing line to pin 1. I haven't checked what the lines are for in detail. But it certainly doesn't contribute to the function if they aren't connected. It has now been neatly repaired with short wires. And I will get completely new ICs, all standard types. Also I have to check whether it is not a deliberate mod, but IC 2 (first pic) doesn't look like that imho.

Ok, so firstly Super proud of the gravity form I am just about done with. Loading technically working up in REAPER so I can edit that and then finish this form at the same time. #SundayWork.
Off to work. Have a relaxing Sunday. 😊 #sundaywork #ineedmoney #nosleeptilwednesday
