I was curious if anyone recognizes this punched card reader. Marked: AMP Incorporated - SYSCOM Division. Can't help with the identity, but I'm loving the 9 edge hanging out the front in contravention of the instruction label! :) Apparently AMP didn't know the "face down nine edge first" song...

Face down: since card readers deal off the bottom of the deck, that puts the first card first. for burial, I can moon the world, or they can kiss my ass. 9 edge first puts the cut corner on the outside, where it is visible, to notice if a card is turned. I have seen corner cut on either left OR right upper corner. I don't recall seeing any with both corners cut. -- Grumpy Ol' Fred ci...@xenosoft.com

I do remember cards with no corner cut, and also with pointy corners rather than the usual rounded corners. Some devices would feed 12 edge first. I vaguely remember IBM reader/punch units where one went 9-edge first and the other 12-edge first. Then of course some card devices feed the narrow edge (1 column) first rather than the top or bottom row. CDC had a reader that worked column-wise and a punch that worked row-wise, so the interface logic for the punch needed a transpose operation while the reader doesn't -- given that both would transfer card data as a word per column. But Electrologica used the same hardware without the transpose logic in the controller, so the software would see columns from the reader but would have to construct rows to send to the punch. paul

CDC 405 reader and 415 punch. Both pretty noisy, but I found the 415 more aurally irritating--and easily overheated if you ran a big punch job. Early IBM gear read only the first 72 columns of an 80 column card; hence the restriction for early FORTRAN to 72 columns. Made sense reading row-binary into 2 36-bit words. Generally, the 405 was very fast and trouble free--until a card was fed that got stuck in the works, resulting in lots of "accordion pleated" cards in the stacker. It was a marvel of engineering, with its machine-gun rattle of 1200 cards/minute. You could load two boxes (4000 cards) in the hopper. --Chuck
