Hi all again, a new CP/M machine is going to be added to my "collection". A Cromemco C10. I'm considering an exchange with another collector, giving away a working msx2. The question is, since the c10 is not fully working, considering if fixing it is in my power. The symptoms reported from the actual owner, who says he repaired the psu, are the following:
1) The machine turns on
2) connecting a working keyboard from another C10 the cursor appear on screen and it beeps 2 times but no
Keyboard: USA1, version 07
Cromemco CROS, version 1.05
message is appearing and it stucks ther with the cursor on screen
3) by pressing a key on kbd the cursor disappears for a few and reappears (key press detected)
4) The machines comes with an eprom instead of the original ROM, but replacing it with the ROM from a working machine it keeps giving same symptoms
attached are some photos of the machine,
If some of you have some tip/suggestion on the potential problems or on how to proceed for a diagnose and maybe a fix is welcome, thank you
