This is an (incomplete) list of
Digital Equipment Corporation VAX computers and specifications.
Compiled by abs@NetBSD.org with much help from port-vax@NetBSD.org users.
This is very much still a work in progress - many sections are little more than
placeholders. Having said that, there should be enough here to prove useful.

| Notes: |
ASMP dual CPU system comprising two VAX 11/780s connected via a (MA780?) 4Mb shared memory cabinet. Apparently faster when split back into two VAX 11/780s. |

| Notes: |
Custom-made for specific applications; probably no more than 10 ever produced 4 11/780s joined by MA780 multiport memory |

| Notes: |
Later, faster version of the VAX 11/780. The final machines in the 11/7x0 range would have been the 11/790 and 11/795, but were renamed the VAX 8600 and VAX 8650 respectively. |

If it existed at all, it was two VAX 11/785s connected in an ASMP system. May have been sighted in Australian Defence Department |
