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.

Last updated: 2003-07-17
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).
