Talk:IBM 7090

message: 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.

message: The memory system of the 7090 had a local control which included a storage clear button. The machine at Pine Hall was placed so that the memory was towards the rear but the computer operator could be glimpsed by a double reflection. When a certain unpopular programmer had dedicated machine time, one of his enemies would sometimes wait until he heard the card to tape operation finish. The core was then placed in local mode and cleared while the CPU was stalled waiting for the input tape to rewind. If the programmer/operator became suspicious his approach could be detected by watching the reflection in the glass panel which covered the core stack.Rdmoore6 (talk) 22:05, 18 December 2008 (UTC)

message: IBM had the contract to operate the 7094s at Goddard during the Apollo Missions thru Apollo 12.  One of the most frequent programs ran on these computers were differential correction.  Each run took about 2.5 hours to run, which was great for a computer operator going to college.  The console of the 7094 could be used to spread out books while doing homework during a differential correction run.  —Preceding unsigned comment added by Afoster5728 (talk • contribs) 14:01, 28 February 2009 (UTC)

message: 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.

message: I worked in SFOF at JPL on Mariner 4 in both "bus" operations and computing, and I'm pretty sure the 7094's on the 2nd floor of SFOF were twin 7094-7044 DCS (Direct Coupled System), not what is stated in IBM_7090#Notable_applications. (I personally didn't know of any other 7094's at JPL.) John Navas (talk) 22:45, 22 February 2011 (UTC)

message: There is a request for citation regarding the name.
I have always heard it pronounced "seventy-ninety" despite the origins of the number as the 709-T (transistorized). I have no citations, though.
In most "citation requests" I see, they seem obvious enough to me, but in this case I would really like a real citation. Gah4 (talk) 18:30, 8 August 2013 (UTC)
replies: text: My recollection is the same as yours, but here is a link  to a much younger Fernando J. Corbató in 1960 explaining timesharing and he pronounces it "seven-oh-ninety," (at 8:12) as does the announcer in the beginning. I'll try to work that in.--agr (talk) 20:23, 8 August 2013 (UTC)

text: I did some Googling in hope of finding something concerning the naming and found this entire article as-is here and was wondering if it was copied from there or is it vice-versa?--Bolbololo (talk) 15:14, 12 May 2016 (UTC)
replies: text: I was about to comment on this, when I see that I did five years ago. The article seems to indicate that it is always pronounced as seven-oh-ninth, and it is likely that some people did. The ones I know called it seventy-ninety, and likely some said all four digits.
I used a 7094 at the University of Maryland and a 7090 at a Navy research center, and they were pronounced "seventy-ninety-four" and "seventy-ninety." I've heard the "709-T" story orally, but it is not mentioned in any written IBM history that I've read, so we really do need a source for this. Rochkind (talk) 16:02, 4 July 2019 (UTC)
thread_title:  Pronounciation 

message: In an edit summary, someone wrote: The noun IBM 7090 is singular as is 709, 360, 370, 3033, 3090, 4341, z/90 et al.  Specifically, the terms refer to the general architecture of the system, and not any specific implementation.  That is also why the terms are used in the present tense, unless they are used in the context of an event.  There could be some cases referring to multiple specific machines that would be plural.

message: There are indications of the first installations of machines, but not for the last.  I wonder, when did IBM stop selling and/or leasing them? Should this also be in the article? Gah4 (talk) 20:35, 30 March 2019 (UTC)
replies: text: IBM withdrew it on July 17, 1969. I've added that date to the intro.--agr (talk) 13:12, 24 July 2020 (UTC)

The lead states  but IBM 7090#IBM 7094 states ; which is correct? Shmuel (Seymour J.) Metz Username:Chatul (talk) 15:53, 24 July 2020 (UTC)
replies: text: Per the manual, the 7094 II was almost twice as fast as the 7094, i.e. almost 4X the 7090. I've updated the text.--agr (talk) 16:27, 24 July 2020 (UTC)
