Talk:IBM 7090

From Wikipedia, the free encyclopedia

The 7090 was the first to bear the new 4-digit IBM model numbers. Rumor has it that originally, this transistor version of the vacuum-tubes 709 was to be named 709T, which was pronounced "seven-oh-nine-tee", and thus gave someone the idea to call it seven-oh-ninety, i.e. 7090.

SABER the first beta edition of AA Sabre (computer system) finished in 03/1959 working in a IBM 7090 System and in a final edition in 1962 SABRE on wikipedia spanish--Mnts 00:47, 10 Feb 2005 (UTC)

I believe that rumor to be true. One of my jobs in 1959, at IBM Service Bureau, was to upgrade the IBM 705 program that held the equipment inventory, from 3-digit fields, plus a one-letter type designator (as "T"), to 4-digit fields, and I believe a two-or-three character type designator. That meant we had to invade the card-sequence number field (cols. 73-80), making reversal to a card-based inventory risky. But we and management were brave.

[edit] Wright-Patterson AFB system

The research labs at Wright-Patterson AFB had a pair of systems, one 7090/7040 lashup, and one 7074/7044 lashup, in the 60s. Played on them quite a bit as a co-op back then.

In the early 70s I worked with a guy at RCA Camden who had been involved with the initial programming the BMEWS computers. Apparently the software was stored in E-core wire ROMs rather than being loaded from media, making debugging and bug fixing a royal PITA. drh 16:17, 10 August 2007 (UTC)
