Ok, thanks everyone I got it powered up, and found some more "SIMMs" for it 
(aka Giant Memory boards but not so big as my VAXen :-) and it things it 
has 224MB of RAM and a PMAGB-BA video interface. The SCSI and ethernet are 
the PMAZ and PMAD ones and appear to be supported as well.

Now an interesting question, I removed the frame buffer, got to the serial 
console, and typed "setenv console s" and re-installed the framebuffer. 
When it POSTs the frame buffer complains about a "red screen test" and then 
the >> prompt appears. Doing a cnfg 0 shows the buffer, what is this error 
and should I worry about it?

Do I need to spoof the mouse to get this to boot?
