re: http://www.garlic.com/~lynn/2017.html#37 Paper tape (was Re: Hidden Figures) we eventually put 1443 on 360/65 for keeping up with console output, things got so that 1052-7 couldn't keep up with all the messages ... and so had to be filtered down. 1401 was low/mid-range ... 70xx was high end https://en.wikipedia.org/wiki/IBM_705 The IBM 700/7000 series has six completely different ways of storing data and instructions: First (36/18-bit words): 701 (Defense Calculator) Scientific (36-bit words): 704, 709, 7090, 7094, 7040, 7044 Commercial (variable length character strings): 702, 705, 7080 1400 series (variable length character strings): 7010 Decimal (10 digit words): 7070, 7072, 7074 Supercomputer (64-bit words): 7030 "Stretch" ... a 360 was to merge commercial & scientific in single architecture 360s came with various additional microcode features that implemented earlier architectures http://ibm-1401.info/1401in360.html#360-1401MicroCode some of my old posts on 360s with microcode feature that implemented earlier architectures http://www.garlic.com/~lynn/2006q.html#55 Was FORTRAN buggy? http://www.garlic.com/~lynn/2009b.html#71 IBM tried to kill VM? http://www.garlic.com/~lynn/2009h.html#52 IBM 1401 http://www.garlic.com/~lynn/2009l.html#10 August 7, 1944: today is the 65th Anniversary of the Birth of the Computer http://www.garlic.com/~lynn/2009p.html#74 The 50th Anniversary of the Legendary IBM 1401 http://www.garlic.com/~lynn/2009r.html#56 You know you've been Lisp hacking to long when http://www.garlic.com/~lynn/2010p.html#11 Rare Apple I computer sells for $216,000 in London http://www.garlic.com/~lynn/2011e.html#53 You almost NEVER see these for sale, own a 360 console http://www.garlic.com/~lynn/2011g.html#70 History of byte addressing http://www.garlic.com/~lynn/2011n.html#84 Scanning JES3 JCL http://www.garlic.com/~lynn/2013l.html#69 model numbers; was re: World's worst programming environment? http://www.garlic.com/~lynn/2014.html#23 Scary Sysprogs and educating those 'kids' http://www.garlic.com/~lynn/2014e.html#17 System/360 celebration set for ten cities; 1964 pricing for oneweek http://www.garlic.com/~lynn/2015b.html#15 What were the complaints of binary code programmers that not accept Assembly? http://www.garlic.com/~lynn/2016d.html#73 Is it a lost cause? -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
