Hardware Documentation - Machines DEC - VAX hardware reference

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.

VAXservers

(Previous - VAXstations) (Next - VAX 700 series) (Main Index) (All Indexes)

VAXserver 3100 KA41-B (VAXservers index)

Nickname: (?) Cpu: KA41-B, CVAX (90ns), 1KB on chip cache, (32KB external cache?)
Vup: 2.4-2.8 (??) Tps: 19
NetBSD: Can run NetBSD Last updated: 2003-07-17
Notes: Created either by replacing EPROM in a MicroVAX 3100 M10 / MicroVAX 3100 M20, or flicking switch on VAXstation 3100 M30 / VAXstation 3100 M40 (?)

VAXserver 3100 KA41-E (VAXservers index)

Nickname: (?) Cpu: KA41-E, CVAX+ (60ns), 1KB on chip cache, (32KB on chip cache)
Vup: 3.5 Tps: 22 (? maybe 30?)
NetBSD: Can run NetBSD Last updated: 2003-07-17
Notes: Created either by replacing EPROM in a MicroVAX 3100 M10e / MicroVAX 3100 M20e, or flicking switch on VAXstation 3100 M38 / VAXstation 3100 M48 (?)

VAXserver 3600 (VAXservers index)

Nickname: Mayfair (?) Cpu: KA650, CVAX (90ns), 1KB on chip cache, 64KB external cache
Vup: 2.8 (?) Tps: 21 (?)
Bus: Q-bus (?) Memory: Maximum 64MB (4 boards) (?)
Enclosure: BA213 NetBSD: Can run NetBSD
Last updated: 2003-07-17
Notes: Appears to be identical to the MicroVAX 3600 (specs copied across), and VAXserver 3602

VAXserver 3602 (VAXservers index)

Nickname: Mayfair (?) Cpu: KA650, CVAX chip @ 90ns, 64KB external cache (?)
Vup: (?) Tps: (?)
Bus: Q-bus Memory: (?)
Enclosure: 2 * BA213 NetBSD: Can run NetBSD
Last updated: 1998-01-25
Notes: Effectively two VAXserver 3600 (or MicroVAX 3600) CPU boxes sharing a single RA82

VAXserver 3900 (VAXservers index)

Nickname: (?) Cpu: KA655, CVAX+ (60ns), 1KB on chip cache, 64KB external cache (120ns)
Vup: 3.8 Tps: 30
Bus: Q-bus, DSSI bus (Max 3.3MB/s) Enclosure: H9644 system cabinet
Interfaces: 1 or 2 ethernet Memory: Maximum 64MB (ECC)
NetBSD: Can run NetBSD Last updated: 2003-07-17
Notes: same as MicroVAX 3900?
