Jay,
Do all of those machines use the same power supply? I know where there
is a HP 12797 (or 12979?). It's an I/O extender for the HP 1000. It looks
like it has the same card rack and power supply as a 1000. I can probably
get it cheap if you need it. It has a DCPC card in it but all the other
cards look like interface cards for external IO.
