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.

MicroVAX I(MicroVAXes index)
Nickname: |
Seahorse |
Cpu: |
KD32, UV1 (250ns), 8KB on chip cache |
Vup: |
0.3 |
Bus: |
Q-bus |
Memory: |
1MB, Maximum 4MB |
Enclosure: |
6" x 28" x 22" |
Introduced: |
1984 |
Image: |
MicroVAX-I |
NetBSD: |
Cannot run NetBSD (As of 1.6.1) |
Last updated: |

Notes: |
Effectively a VAXstation I without graphics. Was the first 'subset' VAX. Used a custom data path chip and off the shelf TTL components. Came in two versions; one includes F_floating and G_floating instructions, the other F_floating and D_floating instructions. Neither version includes H_floating instructions. The MicroVAX I procesor includes some of the optional string instructions (CMPC3, LOCC, SCANC, SKPC, and SPANC) but does not include any of the optional processor registers or PDP-11 compatibility mode. It uses 8K words of 39bit wide microcode running at a 250ns cycle time. |

Notes: |
Can be made into a VAXstation II by adding VCB01 (QVSS), or a VAXstation II/GPX by adding VCB02 (QDSS). Was also available as a 'reduced configuration' VAXstation-II/RC in which some of the backplane was filled with glue |
