As well as the Qbus devices, a lot of the chips used in the DECstations were
also used in VAXstations. The only one that I know in detail (the old
VAXstation 2000) uses all the same chips as the DS3100, except for the disk
and SCSI controllers (and cpu, of course:-).

As such, ports to various VAXstations should be able to reuse DECstation
drivers too.

Have fun with it, rick
