We have a quantity of STD Bus cards, and STDbus chassis. We'll pick more up from time to time, but my complete STDbus inventory should be on this Web page. MOst items are for sale. Some systems are shown which I may not sell, I'm looking for more information and comment and other owners. Items sold are offered AS-IS NO REFUNDS at modest prices - ask for a quote. These cards are not tested but are generally in good condition and undamaged. We will describe their visual condition, usually offer photos.
We also have some original STDbus documentation. Generally we make copies of documents for 20 cents per page plus postage and handling if paper copies wanted. This price may change without notice.
In addition, I have some Intel 4040 based Prolog brand cards and docs. They are not STDbus but they are very similar. These cards and docs are not for sale currently, but I can provide copies of docs.
The STDbus was developed in the mid-1970's by ProLog and Mostek as a 56-pin bus on small cards. It became an IEEE standard known as IEEE-961 in 1987. Compatible cards were manufactured by many companies in the 70's and 80's. The bus was extended to 32 bits with a dual-use 136-pin edge connector and called STD-32 in 1990. 56-pin cards became differentiated between STD-Z80 and STD-80. The STD-80 spec provided for 16-bit data paths and 20 address lines by multiplexing data and address, useful for 80286 and 68000-class processors. STD-Z80 refered back to the earlier non-multiplexed design, by then used mostly on Z80 processor-based designs.
STDbus Web links: Some STD bus cards are documented on these sites:
(many Versalogic cards are compatible with Analog Device cards, other brands)
ZiaTech stuff is at this link.
This document describes STDbus history and features.
WinSystems stuff is at this link
Here is an image of some STD bus prototype cards; left to right, Prolog 7904, MicroLink 97130, Prolog 7900.
We have some other old computer cards as well. Check my STDbus, VME, & Multibus page for links to those items, and to my S-100 and Mac and SGI stuff as well. Here is how to email @ me and ordering instructions.

The following STDBus cards were acquired a few years ago. Many of them are unused and sealed in antistatic bags, some opened and unused or lightly used, a few show some use. We'll tell you what we see when you ask for specific cards. The number on the far right is a count of boards.

I have a bunch of card cages and chassis that can or do hold backplanes, power supplies, etc. Check my Web page of cages and chassis. Some specific STDbus cages, chassis and backplanes are listed on this Web page.
STDbus card cage, backplane with 16 slots. One available.
Prolog brand STDbus card cage & backplane with 8 slots. One available.
Prolog model 721C, STDbus card cage in cabinet, may also bee BR16-T 7000 CCD 107488 Rev B. Has 13 slots, AC power supply. Here's the back with AC and fuse. We have four of these.
one boxed, Vector brand 4610-8-3 STDbus backplane, 8 slots, unassembled kit. No chassis, just the backplane. $49.
Vector brand CCF-13 card cages, will hold STDbus cards, possibly others if user-modified. CCF-13 card cages are equivalent to today's Vector brand CCA13M/90 cage with metal card guides. Check Vector's Web site for description for a catalog description. I have several of the CCA13M/90 cages unused in original shipping boxes. Cage is 5.23" high, 9" deep, and 19" long (rack mount). Box is slightly larger. Cage holds 21 cards in metal slots 3/4" apart. Supports 4.5" x 6.5" circuit boards such as STDbus cards (photo) or classic Vector 3662A6 or 3662-9 with 44 pin edge connectors. Backplane not included. $49 plus shipping each, shipped in original box.
I have used card cages similar to the Vector's as above, with a horizontal door. This photo shows the cage, for 19-inch rack mounting and about the same dimensions as the Vector cage above. There's 11 slot guides, more could be added. The depth of these guides is comparable to the Vector cage, but the rails are closer to the front of the unit. Two of these used cages are available at $39 each plus shipping.
Here's a photo of a disassembled rack, easy to ship. If interested I'll provide dimensions and details.
Another used card cage with door: a rack with point-to-point wired 44pin connectors and door. $49 each plus shipping, with connectors.
