The CPUs are different. IIRC VLC is a SOC, VS4000-60 is a Maraiah and
VS4000-9x are all NVAX. The SCSI controllers and ethernets may well be identical 
- I don't have that info handy. But someone would have to do the CPU work first 
(and, AFAIK, none of those CPUs are used in any currently supported NetBSD VAX 
platform).

Donate a VS4000-90 and I'm sure you'll find plenty of volunteers :-)
