Ah!!! Thank you. I know that Nathan Mates posted that information earlier,
but my brain wasn't reading it properly. I thought he meant switches one
thru six. ;)

I had a look at their web site, and got more information on what I need.
Unfortunately, they won't supply the one thing I do need, which is a copy
of the Transwarp ROM, either 1.7 or 1.8. I actually have two of the 8k
cache boards, soldering skills, tools, parts, etc, but no ROM data to make
it work. Naturally with all that material already in my posession, I'm not
motivated to buy more of it from overseas.
Anybody out there kind enough to E-mail a copy of the Transwarp ROM 1.7
or 1.8? Or in a pinch, I can Snail-mail you a copy of my own 1.5 ROM,
and I can "get an upgrade"?
Many, many thank you's to everybody who's E-mailed me and posted.
