Pro-Log manuals for Intel 4040, 4004

Last update Aug 30 2007.

My home page for Multibus, VME and STDbus stuff is linked here. My S-100 home page is linked here.

We provide good photocopies of original technical manuals, related to old microprocessor equipment. To email @ me for details, prices, questions or to order, check my ordering page.

I acquired these Pro-Log documents and hardware in 2006 from a biology researcher who built a 4040 system in the early 1970's to control a lab instrument. In 2006 he retired and shut down his lab, and generously offered me his equipment. Details as I learn more about these things, when time permits.

Pro-Log documentation

all documents were produced by Pro-Log unless noted. Documents of a few pages are product brochures with features, edge connector pinouts, general specs.

I have a 1973 version and a 1977 version of Pro-log's The Designer's Guide to Programmed Logic. The 1973 version is 4004 based, the 1977 has the same material updated for the 4040 as well and those then-new products. The 1977 version has 140 pages and is in a 7 inch by 9 inch format.

It describes the processor instruction set, basic features of the Pro-log cards, and then a tutorial on how to program in HAND-ASSEMBLED 4004 or 4040 code. The tutorials cover issues like subroutine calls (due to the limited stack), TTY I/O, and some arithmetic routines. Several pages are tables for fractional values in decimal and in hex. Strange to see all this, but in the early 1970's, engineers did not have access to computers for cross assemblers and so forth. The 4040 and 4004 were intended to replace control logic, not as actual "computers" themselves.

There is not much on hardware design, as the modules do most of that for you. But the modules use the Intel 4000 series chip set, so the information is informative in general.

I can copy it in an enlarged format to 8.5 X 11 sheets, "letter size" paper in the USA. Otherwise I can copy it at actual size but there will be blank margins on the larger paper. Let me know your preference, contact me for copying and shipping costs.

Other 4004 or 4040 documentation

I have an Intel databook, MCS-40 USer's Manual for Logic Designers from NOvember 1974. It describes some 4040 series chips at the hardware design level, some 4040 assembly and binary programming information, and a very little bit on the Intellec 4/40. I'd estimate it to be 120 pages, and its a softcover which measures 7 by 9 inches, like most of the Intel manuals of the period. Contact me for copying and shipping costs as described for the ProLog document above.
