Intel Multibus items

This page last updated July 15 2010.

This Web page describes the Multibus I resources I have, mostly manuals and Multbus I cards, card cages. Other information including resources other people have, can be found at this linked page. My general Web page for Multibus, VMEbus and STDbus items is on the linked page. To email @ me for details or to order, check my ordering page.

My understanding is that Intel sold their rights and licenses for Multibus I and Intel's Multibus I products. For the history of Intel's Multibus license holders, check my early Intel history page.

I have a part number list of old Intel manuals. Follow this link for the .doc file.

As of 2008 I have a working Multibus I system. Check this linked Web page for specifics.

Multibus card cages

this cage and power supplyare from Monolithic Systems. Seven slot Multibus card cage with backplane, no P2 bus. Also corresponding power supply, open frame (not switching) type. Pulled untested. These are rack mount, not deep so you can mount cage in front and powersupply in back. We may keep this for use so we won't give this away. Ask about a quote otherwise.

Intel documents

I have these documents. Good photocopies are available from me for a modest fee, contact me for details.

Intel Handbooks

From the beginning of Intel, they published "handbooks" documenting chips, software, and hardware. These were softbound books about 8 inches by 5 inches; a common format in the 1970's and 80's before the Web and CD-ROM's. I have a collection of these from Intel from that period. As time permits I'll list them here and try to provide some details. Some of these may duplicate component data sheets which were also published in 8.5 X 11 inch format.

My terms for photocopying these is that I'll provide one of two formats. Either two 8 X 5 pages per 8 X 11 sheet; or enlarged each 8 X 5 page to 8 X 11 size. The cost will be PER PAGE "PRINTED". So the two half-sized pages on one sheet count as one page, the two half-sized pages on TWO sheets counts as TWO pages. Contact me for prices.

Data sheets, design information, instruction sets.

Intel MDX 432A development system, diskettes, manuals

The Intel MDX 431A system, manuals and diskettes described below was sold in Aug 2006. Information about that system including a list of hardware, manuals and diskettes, are listed on this linked page. Contact me if you are looking for software or manuals from this system, I'll pass contacts along to the new owner.

The Intel system is in a white Intel cabinet, not a "blue box". Multibus I based system with 5" floppy, 5.25" hard drive, monitor, kbd system boots up from hard drive, Intellect IV iNDX ver 2.8 software environment 8088/8089 based system with software and ICE hardware for 8051 development ICE-51 8051 emulator card and pod, with MCS-51, PL/M-51, ASM-51 s/w various original diskettes and manuals for IAPX86, 8085 as well.

Assorted Intel diskettes, manuals for ISIS, Credit, PL/M, iRMX, more!

Intel disks - over 80 8-inch disks, accumulated from various sources. All original. Apparently in good shape.
