I have a Commodore 2088 Bridgeboard in my 2000. You needed Janus
(named after the 2-faced god) to use it or one of several other european
programs I found. I also have an MFM drive in it and what I finally figured out
was a MSmouse card. I've yet to find the time to get it functioning. I am
curious tho as to what's on the PC HD. I guess the original boot-disk had
Janus and other configuration data on it. Other than ignoring the 2088 the
2000(not HD model) runs fine.
I have a spare 2088 that unless Doc or SuprDave want it, is up for trade.
