IIRC, you could punch up a control card that defined tab stops wherever you wanted, auto skip zones and even numeric only areas. As I remember it many of the machines would often stop one space to the right of the defined tab because they never got properly adjusted. That service was reserved for actual keypunch professionals. ;-) > Bonus history question: What do tha accronyms ASR & KSR mean and > what hardware differed between those variants? How bout the RO models, did you forget about them? ;-) Unfortunately I had to suffer thru those days too. Rolls of yellow paper, how convenient and oh so easy on the eyes. Did you ever see a TWX machine? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
