I recently purcahsed my first IIe, so still working things out. After fixing the PSU and replacing the CPU it is up and running, but with a few teething issues.
I added a 80 Col card to a Rev A motherboard, with the understanding that HiRes should work, but Double HiRes not.
Using something like XPS diagnostic the output in 80 Col mode shows spaces are replaced with an *
(Not a problem in 40 col mode)
I don't know if this is correct or an issue? Ideas would be appreciated!
Some of the things I tried:
.Other testing software gives the same issue.
If I plug a borrowed VidHD card in, it does not have the problem on that montitor, but the *'s remains on the composite output.
I tried unplugging all other cards, swapping memory on the motherboard and expansion card out with another set, but it does not change anyhthing.
No other diagnostics on the board fail, I tried various.
The machine details
Apple IIe PAL 1982 820-0073-A (Chips are socketed, so should be the original Rev A)
CPU 6502 (Replaced from another IIE of the same time, slightly newer board)
CD ROM 341-0135 Rev is unclear likely to be A or H (if that even exists) (1982)
EF ROM 341-0134 A (1982)
Video 341-0160 A (1982)
Keyboard Rom 341-0150 Rev A (1982)
The ROM versions printed on the motherboard match the ones plugged in.
Apple AIIE 80 COL/64K Memory Expansion
820-0067-B (C) 1981
J1 for the double HiRes not there. Did not make a difference on the 80Col test if I added it.
