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.

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: 2003-07-17
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

Notes: Same CPU as in VAX 8200, 8300, 8250, and 8350. Digital's first true 3D workstation. Based on the VAX 8200 CPU packaged in a deskside enclosure, the VAXstation 8000 used a sophisticated 3D graphics subsystem designed with Evans and Sutherland. This graphics subsystem consisted of the complete 3D graphics pipeline and additional hardware support for such features as hardware anti-aliasing of vectors and depth queuing.

Notes: Usually shipped with a KZQSA SCSI controller, TK50 or TK70, occasionally a TF86. Can hold up to 4 internal DSSI disks (RF3x or RF7x series), or 3 if tape drive in frame. 256K firmware ROM. Most Q22-bus peripheral devices are supported, as long as a quad-height board doesn't use the Qbus on both halves. (The bottom half is an extension bus.) 7 slots are provided. Uses S-box cards, such as the CXA16 and KZQSA-SA, and RFxxE-AF series disks. Upgradeable to KA690 CPU (requires MS690 memory and backplane upgrade for early machines).
