You might not want to use the original reference disk, as it probably has
been updated since then, and the update will be on the FTP site

As far as an OS, Linux and NetBSD will both work. Linux is a bit more
stable, but NetBSD is the better OS, and the stability will be perfect by
next release, and that should be soon. BTW, Warp 4 should run faster than
Warp 3 with a small amount of RAM like that.

This machine isn't really a PS/2 in the conventional sense. Not a
microchannel box. Which means it's probably less interesting than that

PS/2's are *extremely* common in that HUMONGOUS amounts of them were sold
to (and many are still running at) many financial institutions. They are
beautiful machines that are rock solid, are built like tanks, and never,
ever break.

I believe you should use the latest option disk. BTW, there is no such
thing as an "RS/6000-specific" or "PS/2-specific" option card.
Microchannel is microchannel.

I could give you a copy of my technical docs for this card, if you want.

You're absolutely welcome.
