> 604 to a 403 to a 519. 604 was a tube-filled 5-foot-tall 6-foot-long 3-foot-wide frame of tubes called a calculating punch. Had about 16 "programming steps". We had one and I never saw it used. I suspect it was replaced by the 650. 403 was likely a tab like the 407. IBM had a thing for number sequences. Wonder if it also sounded like a 407 -- a cross between a washing machine in distress and a robot having an orgazm (nanny prevention misspelling). 519 must have been the summary punch attached to the 40x. Could also be wired to copy a card deck. While were on this off-topic, can anyone tell what were the machines that were used for the Manhattan Project (and described by Richard Feynmann in one of his autobiographies -- my ex-father-in-law worked on it, not me)? They sounded like 40x-519 combo. ----------------------------------------- The information contained in this communication (including any attachments hereto) is confidential and is intended solely for the personal and confidential use of the individual or entity to whom it is addressed.
