I recently got out my 8032 and figured i'd do some board work had 3 (8032 MB) to repair. I turned it on got the normal beeps warble screen displayed an odd 7K of ram then died lost display. On reset it was stone dead.
I replaced the 6520(2), 6502, 6522, 6545, the character, kernal, edit, and basic roms.. (yes I have alot of spare parts. The unit now beeps as normal but has no display. I swapped in another baord I had not knowing the status of it and got a dot in the center of the screen so I assume the monitor to work still. Ok back to my original board.
I am thinking the DRAM's might be causing me trouble not allowing basic to post and since I had the odd ram reported when it did come up the first time. Ideas? or thoughts. I think i'll start socketing all my DRAMS now. I love my Hakko 808 for these old boards.
I have verified the voltage 20v going to the monitor the heaters glow, The +5, +12, and -5 are all there.
Thanks in advance for any help.
