re: http://www.garlic.com/~lynn/2011k.html#13 Last card reader? reader ran faster than the punch ... punch had hopper for maybe couple hundred cards (on left) ... reader had slopping tray feed (on the right) could get at least a box of cards (2000) bitsavers more detailed 2540 (but poorly scanned ... hard to make out details) http://www.bitsavers.org/pdf/ibm/360/A21-9033-1_2540_CompDescr.pdf 1402 was similar ... lot more detail & better scan: http://www.bitsavers.org/pdf/ibm/140x/231-0002-2_1402_Card_Read-Punch_CE_Manual_1962.pdf bitsaver is also good for older tab machines: http://www.bitsavers.org/pdf/ibm/punchedCard/ -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
