My CBM 4032 can COLD boot to COMMODOR BASIC 4.0 and the cursor flashes normally. But when I press Enter, the cursor is missing and system hang. No response when I pressed any key.
If I reset system (toggle power switch) after it runs for a while (2-3 minutes) (HOT boot), the beeper will chrip but the system will keep black screen and can't boot into BASIC.
I repalced MOS 6522 and two 6520s, but still got the same problem.
Is this problem relate with RAM chips?
Thanks for your kindly help.
