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.

MicroVAXes

(Next - VAXstations)

(Main Index)

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:	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:	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.
