The infortext system 1977 purchased by AM international about 18 months latter was the first comercial user of the Signetics 2650 processor in its copy control system. I think, I still have one of the origional wirewrap motherboards and a card reader somewhere in storage. The system used credit card size plastic card punched on a modified card punch to provide copy control. My first big instals were at the Navel Air Systems Command in DC. BlueCross Chicago and GE Nuclear in San Jose. We controled copymachines you put your card in, if reconized we enabled the copier and counted your copies and origional changes and using the 2650's onchip uart drove a telegraph based wan connection to a central data logger. To keep their avarage line tarrif low MaBell had never raised the telegraph line terrifs and were not happy when we started ordering hard copper telegraph lines, at $2 to $3 per month for up to 2 miles. When they claimed they were data lines at 10 times that, we demanded they put a scope on one of our lines, they gave in. I spent 13 weeks in San Jose that first year durring the Pacific Bell strike punching my own cross-connects. Other than a few pinball machines, I do not know of any other 2650 based systems. I left Infortext when Addresse-grief Multi-grief came in and anounced the takeover. They called a company meeting of the dozen or so engineering, service, and production people and informed everyone that based on AM's corporate guidelines everyone who was hired by the previous owners was overpaid without exception. All raises and reviews were to be put on hold until we came into line with the rest of AM international based on some new paygrade system. We had all been waiting for raises that were long over due by the cash strapped startup. With the exception of the founders just about everyone found new jobs within a week at most. AM brought one programmer at a consulting rate to comment code code for a while. And one of the production guys had just has a kid and stayed for a while. I had insatlaled about 200 - 250 systems spread from east to west when AM made their move. Some say, AM quickly dumped Infortext in the early 80's, while others at the time claim to have purchased their freedom from AM.

In the manual for the M900 is the source code listing for the EPROMS (1702's). I plan on making one of mine into a 4004 development system someday. It has a keypad, LED display, and some I/O ports.

hmm this list could run and run keep it up chaps, update The Rohde & Shwarz RF test set was an SMPU and was in the 1975 catalogue (I found a copy at home at the weekend) TMS7000 I have one on a Speech option card made by Texas for their Professional Computer Dave Caroline
