"Distributed"? Perhaps, in the sense that there exists DECnet/ELN if I remember
right. (End node only, probably. The LPS40 uses this, I think.)
The KA620 is closely related to the KA630
(MicroVAX II) with one small but significant difference.
The rtVAX family (not to be confusbed with the ftVAX) were sold to run DEC's
distributed realtime OS, VAXELN, which could be network booted (or boot from disk). Some
rtVAXes had slightly cut down memory management relative to ordinary VAXes, a
"feature" which meant they'd never run VMS.
VAXELN is on my "list of things to play with". Still, a BA23 is a QBus
enclosure...I can probably convince someone to give up a processor for it if I don't
like the rtVAX. ;)
NetBSD seems to also have some /posible/ rtVAX support.
I've run NetBSD on VAX (in SIMH). It does basic things but it needs work, partly
because gcc has some code generation bugs.
