Hello!
I repair electronics and just got a MPC2000 handed in by a customer (very interesting case).
I can't seem to find any schematics on the MPC2000, but I see some for MPC2000XL. Unfortunately its not giving me any guidance towards the problem, I hope some in this forum could point me in the right direction.
Problem:
Machine tunes on, but boots extremely slow (20-30min). The LCD is loading in small bits (line by line). When booted every command takes 30 min to load and the test (seen in the manual) takes 3-4 days to run.
What I've done:
- Tested power supply - I have 5V, 5V, 11,8V and 11,4V going out (looks ok to me)
- Changed EEPROM
- Disconnected drive
- Tried booting without floppy
Nothing seems to help the issue.
Really hope anyone can point me in the right direction, so we can save this beautiful machine.
Thanks!
