Today I was cleaning out my room over the garage, which is where I have my home office and my *MODERN* computers. In the process of cleaning out one of the desk drawers, I found an old manual that I knew I had kept since college in the 1970s, but I had lost track of where it was. It's a 1954 "Preliminary Manual of Information" for IBM Electronic Data Processing Machines, Type 702. It's 83 pages long and has lots of interesting information on the 702 system and its related set of peripherals and other items. On page 4 is a picture of an installation, with some 727 Magnetic Tape Units, an operator's console, a 712 Card Reader, the 702 Arithmetic and Logic Unit, a 732 Magnetic Drum Storage Unit, a 722 Card Punch, and a 717 Printer. The main storage unit can hold a total of 10,000 characters, which are stored as dot and dash charges on 3" cathode ray tubes. Does anyone on this list remember this kind of system? It is really interesting reading, looking at this manual and comparing to where we are today, or even where we were back in the 1970s, when I picked this manual up from the "free giveaway" table outside our college's computer room. Does anyone know if this manual exists in scanned form? If not, I'll scan it and send it to Al Kossow to put on bitsavers. Ashley
