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.

MicroVAXes

 (Next - VAXstations) (Main Index)

MicroVAX I (MicroVAXes index)
Nickname: Seahorse Cpu: UV1 (?)
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 1.4) Last updated: 1998-05-31
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.

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.

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).

Multiple types of cables - one from KDA50 to 4 male SDI plugs mounted in host system, thick black 'liquorice strap' female to female cable between host and drive housing, then thinner white male to female cables between the drive housing and the drive itself. Cables swap pins so you must have an even or odd number of cables dependant on the drive. Cables were allowed to be up to either 15 or 30 meters
