I've considered this before, and the PCI part seems to be a sizable 
stubling block.

An ISA card might be an easier way to start off.  I've got access to a 
fair range of machines with ISA slots, from IBM 5150 PCs to PIII 
desktops and IBM RS/6000s to DEC Alphas.

Hmm, a ISA->QBUS adapter in an Alpha, running SIMH and talking to an 
RL02.  This sounds like fun. :)  Or hell, port the NetBSD/vax RL02 
driver (after fixing it so it actually worked again) to NetBSD/Alpha (or 
Linux/Alpha if one was so inclined). :)
