everything in it except the processor shoudl be supported by ultrix (more 
or less). Ultrix does support DSSI. 

arent the memory boards just MS650s?

it is a normal Qbus backplane, you can stick any other qbus machine into it
too

the cabling, as long as it's straight through and doesnt go through
any logic or anything (who knows what's hidded by the backplane) should be
usable. if this is like the BA440 though, with a board with plugs that the
disks connect to, i woudlnt be too confident in it working (and i woudlnt 
want to find out by losing a scsi board to it! who knows what would 
happen! ) but if its just a cable, yeah, 50 pins is 50 pins.. :)

well, check, those were not very common. the groove is only an indicator that
it is meant for a high current feed cable. nevermind it, find a regular 
cable, get a knife, and cut a groove into the plug :)
