I used to work on a 360/20 starting around 1971. We had the basic model - 4K of memory, no disk, no console. Just a MFCM reader/punch and a 300 LPM printer. There were several utility programs on card decks - sort, gang punch repro, and a report generator, plus the RPG compiler. I especially liked sorting. We had some little decks of cards, less than an inch, that had to be sorted on about 15 columns. It was faster than sorting them on the sorter, even thought the sorter ran over 3 times as fast.
We upgraded that machine to 8K of storage, and put on some other hardware and made it into a remote RJE. We ran the jobs throught the card reader, and then printed the reports. I remember one series of jobs that ran almost 24 hours on our 1410 computers ran about 1 hour on the 370 machine we dialed in to.

In the common meaning, it certainly wasn't. To a large extent programs written for one 360 and operating system would operate on other 360 models. That was the prime invention and genius. Since that wasn't true for a /20, it couldn't possibly be a 360. But of course it was sold and labeled as a 360, so it was. A paradox. john +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ This electronic mail transmission contains information from P & H Mining Equipment which is confidential, and is intended only for the use of the proper addressee.
