Not really, AFAIR. OS/360 was introduced in three flavors: PCP (primary control program), MFT (multiprogramming with a fixed number of tasks, and MVT (multiprogramming with a variable number of tasks). All three were in use simultaneously. I don't know what features PCP had, but it was a stripped-down system. Users chose one of the other two based on machine size and their requirements. When VS came in MFT became OS/VS1 and MVT became OS/VS2, basically with virtual storage layered on top of each system's feature set. > > MVT became VS2(aka SVS), MFT became VS1 ... > > VS2/SVS became MVS. > > In any case, os/360 became multiple things ... one of which is > evolving into os/390.

These variants followed in the sequence quoted. At the time when Version numbers were in single figures, Releases came once a month and at the 360/75 customer where I was one third of the systems engineering support we didn't install every Release. Also at that customer we didn't install PCP, the only thing coming out of Poughkeepsie at that time, but an early release of MFT called Admiral, produced by World Trade people in Poughkeepsie. Why? We had sold "360 with MFT" to many customers in Europe! It worked very well until Poughkeepsie caught up, after some traumatic reorganisations. By the way, when MVT eventually arrived, the acronym was explained - MFT was multiprogramming with a fair amount of trouble, MVT was multiprogramming with a vast amount of trouble.

Um...bad phrasing. OS/360 was in effect an umbrella within which one could find PCP, MFT (later MFT-II), and MVT. I think you meant to say that OS/360 initially had only PCP, then added MFT, then (at release 12) introduced MVT. For the benefit of readers who never had the pleasure of performing a SYSGEN, all three flavors of OS/360 were generated from the same set of macros (similar to the DOS/TOS generation procedure).

R12. One of the side-effects of the addition of MVT was that the entire source set for OS/360 was resequenced. My shop didn't have a big enough machine to run anything more than MFT (we had a 360/G40) until late 1969, when we installed a 370/I65 (512 KB memory) and used MVT with HASP. (Talk about tight memory: MVT plus HASP we finally shoehorned into 256 KB, and I used just about every trick I could play to make that happen...we did this because we knew that we would be getting more memory in mid-1970 and didn't want to make the users learn a new environment twice in a year.)

When counting, my 2.5 year old nephew seemed to be prejudiced against the number 5. I see a similar cause for not mentioning the 360-85. Possibly because it was a "near" 370 (block multiplexor channels, Rotational Position Sensing). ###### From: "John Bowen" Newsgroups: alt.folklore.computers Subject: Re: is this correct ?

I installed the first 360 outside of IBM. I was a Customer Engineer at the Top Secret Rand Corporation. In May 1964 and I installed serial #27 with 64K of RAM (360/40). We ran PCP for a bit and realized we were dying because our input device was a 1442N1 card reader (I think it was serial #3). A couple of software modifications put our card images on 2311s (also the first to leave IBM) and we edited the card images as we developed software for what became the Rand Tablet for DARPA. We should have thought of the mouse. We used PCP for a year or two because MFT was not reliable at that time. A year later one guy in my group (Paul Baran) had an idea for packets of data on a network. We thought it was not worth much but today we call it the Internet.
