Hmm. Ok.
(it is odd that when it asks me to mount the disk, the
!'s
are
inverse...as soon as I put the disk in, they become
normal-video !'s.
That's supposed to happen. OK, well, without the !'s, that is. It's supposed
to go to a white screen asking for the disk.
How easy is it to pull those chips and swap them
around?
Extremely, extremely easy. Just use a tiny flat blade screwdriver to gently lever them up
and out of their sockets. Note the direction - that the chips are installed in, it's
important they stay oriented the same way around.
Actually, before you try swapping chips around, just pull out the video board and firmly
press down on all the socketed chips, to seat them down into their sockets - sometimes
things come loose. If that doesn't do anything, then swap the RAM chips around - swap
U21 and U22 with U19 and U20.
Looking at the web page, do I need just plain
2114's?
(I see several
variations of them including different speeds and low-power
etc)?
Should be. Don't know the speed on the ones used in the Model II, but I seriously
doubt it's anything different than normal ones.
