re: http://www.garlic.com/~lynn/2013b.html#43 Article for the boss: COBOL will outlive us all http://www.garlic.com/~lynn/2013b.html#45 Article for the boss: COBOL will outlive us all http://www.garlic.com/~lynn/2013b.html#51 Article for the boss: COBOL will outlive us all 7094/ctss, cp40/cms, cp67/cms, etc were online, interactive system with 1052s, 2741s terminals (not card/keypunch batch systems) ... which were upper/lower case selectric typewriters with computer interface. http://www.multicians.org/thvv/7094.html from above: By 1963, CTSS provided remote terminal service to dial-up terminals connected by modem to a specialized telecommunications computer, the IBM 7750. Model 35 Teletypes were used at first, followed by IBM 1050 terminals and IBM 2741s. The 7750 and the IBM Selectric terminals were designed for other uses, such as stock trading and airline reservations, and CTSS adapted to the design of these devices. CTSS did specify that certain RPQs had to be added to the 2741, so that its keyboard would not lock up after every line, and also required that remote terminals on CTSS have a "terminal ID" that would be sent at dialup time. CTSS users would look at the output of Noel Morris's who command to see where their friends and colleagues were connecting to the system from. Terminal access for Teletype terminals was at 110 baud. The 1050 and 2741 terminals could support 134.5 baud. All of these devices were supported over dial-up modems, accessed via a private phone exchange at MIT. ... snip ... i had 2741 terminal at home from mar1970 to summer 1977 ... when i switch to 300baud cdi miniterm. cp67/cms delivered to univ. jan1968 had 1052 & 2741 terminal support. univ. had some tty terminals ... and i added the tty terminal support. http://www.multicians.org/thvv/360-67.html i had done hack with one byte arithmetic line-length limited to less than 256. above mentions Tom changing configuration to specify (i think ascii plotter device down at harvard) max line length of 1200 chars ... but didn't fix the instructions using one byte cms script (done mid-60s port of ctss runoff) was documentation preparation ... was extensive upper/lower case. one of the early major ibm documents moved to cms script was principles of operation. The full documentation was the architecture "redbook" (for distribution in red 3ring binders). cms script command line operation would produce the full redbook or the principles of operation subset (i.e. full redbook had lots of extra detail in each section and every instruction description). then gml was invented at the science center 1969 (g, m, & l chosen for the first letters of the last names of the inventors) ... and gml tag processing added to cms script. some past posts http://www.garlic.com/~lynn/submain.html#sgml decade later, gml morphs into iso standard sgml. another decade, sgml morphs into html at cern ... http://infomesh.net/html/history/early coming full circle ... first webserver in us (outside europe) was on the vm370/cms system at slac http://www.slac.stanford.edu/history/earlyweb/history.shtml -- 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
