I just got my first II plus and so far things are going pretty well.
I've upgraded the PSU, and I put in a ROMX. The old ROM under the keyboard was a dianetics lowercase ROM, but I pulled that to install the ROMX completely. Presumably due to changing that ROM, I found intermittent boot behaviour with the mystery card in slot 3 which appears to be a generic 80 column card w/no cables. I pulled the (presumed) 80 column card, and things are pretty good.
my system has a microsoft lanugage card in slot 0 right now. The instructions for installing the UltraWarp say to use slot 0 for a II or II plus, or any slot on a IIe. Problem is if I pull the microsoft language card, I'll have an empty RAM DIP socket directly under ROM F8. I assume I will need to get a RAM Chip like the ones next to it to replace the empty socket, before trying to install the ultrawarp?
The only other cards in the system, presuming I replace the language card with the UltraWarp and leave out the mystery 80 column card, would be a 5.25 disk controller and a ReActive Microdrive turbo. Perhaps a super serial if I can find a ternimal app, but proterm want's a IIe to run.
Also, are there any decent 80 column cards I can find that would/should work fine with the ROMX?
