Is the daughter card the same as used in the early 3100 lines?  If so,
then I have sufficient to get the thing up to the mb and a daughter card.
I have not opened the critter, but wanted to make sure before I blew
something's sillyconsmokum, with a wrongo hookup.

Mine has an undercase cabinet (maybe 1.25 inches high) that has a B
connector of 50 pin DB connect, and a C connector of ``Centronics''
which I assume is for the scsi.

Can it boot cdrom, or will I have to netboot or tapeboot the thing?

Hmmm, I will keep that in mind.
