Hallo Chandra, > (1) take a "abnormally" long time for the cursor to come up and start > blinking after powering on RESET-circuit ? What happens if you reset the 2001 in the hard way eg by connecting pin 40 of the 6502 directly to GND. (won't harm if you don't do it too often) > (3) Almost within 30 sec the cursor either stops blinking or is solid and > the computer locks > up...any ideas on where to look? IRQ is responsible for the blinking of the cursor AND reading the keyboard. AT this moment I don't know what IRQ-source the 2001 uses (6532, 6520, 6522), so replace this one at least. Another check: 10 print"x"; 20 for i = 1 to 200 : next : goto 10 If it is the IRQ, then above PRG must keep on running. If it is more critical, the PRG will stop as well.
