Okay, as long as I can forward this to alt.folklore.computers. :-) As I mentioned, the act of reading core memory cleared all 37 bits (the discussion centered on a PDP-10, a 36 bit architecture). Reading cores entailed impressing a magnetic field strong enough to set all bits to 0. the flux change in the 1 bit cores would be read out from the sense line. If power failure or logic glitch resulted in the data not being rewritten, then the the memory location would be left with a zero parity bit and zero data. Hence, writing odd parity and verifying for that would let you catch any read-forget-to-write cycles the memory system did. Paper tape, on the other hand, was often typed by hand on Teletype models ASR 33 and 35 or, before them, on Friden Flexowriters. Typein mistakes could be "rubbed out" by positioning the tape at the offending character and pressing the rubout key which perforated all the holes. On ASCII Teletypes, this meant 8 bits of ones, or even parity. So RS232 and current loop systems always expected even parity and would complain about odd parity characters. It was a big advance when people developed editors capable of reading a paper tape file into memory, let you edit it, and then punch the new version. Paper tape on TTYs came in rolls of yellow paper, on fancier and faster devices, it came in boxes of "fan-fold" tape.

This made it unsuitable for use on optical > readers. Hence the oil-free fan-fold tape. Oil impregnated paper tape did indeed exist, but was mostly related to a pre-computer age. The oil assisted the old mechanical readers on machinery such as the Tape Transmitter No.1 used on 5-hole baudot circuits. Paper tape in rolls was most certainly available in non-oiled form, and I have used many thousadns of rolls of it, in 5-hole, 6-hole, and 8-hole widths, using both mechanical readers (e.g. in off-line tape reproducing stations, using the aforementioned Creed Tape Transmitter, or with the Teletype ASR33) and with photoelectric readers.[1] The fan-fold system had one measuable advantage over "ordinary" tape, and that was that one didn't need to rewind the tape after use. However, fan-fold couldn't rally manage the sizes of tapes that were sometimes used in data collection and storage, where often the whole of a 1000ft tape might be used for one data set. IIRC, the maximum contiguous length of fan-fold was only about 200ft. [1] At a guess, the tapes that Colossus used to read photo-electrically, at 5000 ch/s, were most probably oil-impregnated, because at that sort of date all rolls of paper tape were of that variety.

Garbage cans were used for fanfold tape on PDP-10s, too. The "hopper" for the tape was too small. When the hopper was 3/4 filled, the operator would _very carefully_ remove all but 10 fanfolds and put it somewhere.

Most high-speed readers in the UK were like that, except that the standard rolls of paper tape were not oil-impregnated - in fact, I never saw any that were obviously so. It was commonly said that fan-fold paper tape was invented by USA engineers who were instructed by management to produce a better paper-tape reader. So they invented a sort of linked punch card system and wondered why it didn't work very well :-) Whatever, the truth, the fact is that fan-fold paper tape always was a crazy idea, as rolled paper tape was earlier and better. But it was fairly rarely handled well in the USA, though it dominated in the UK for a very long period. In fact, at Cambridge, paper tape outlasted punched cards - it was used for controlling the Mullard radio telescope and was used until that was decommissioned on the principle that, if it ain't broke, don't fix it. The reason that paper tape got a bad reputation in the USA was that IBM and others made bloody awful paper tape equipment - that was the same reason that punched cards got a bad reputation in the UK! I could tell you stories about the ICL card reader from hell .... Regards, Nick Maclaren, University of Cambridge Computing Service, New Museums Site, Pembroke Street, Cambridge CB2 3QG, England.
