IBM PC system meant something different back then :) Here's the list, for Norm, Erik, Dave and anyone else who inquired or may be interested; a little musty but generally in good shape. REFERENCE/OPERATION MANUALS 24/26 Card Punch/Printing 46/47 Tape-to-Card Punch 56 Card Verifier 65/66 Data Transceiver/Printing 77 Collator 2, 1 no cover 82/83/84 Sorters 101 Electronic Statistical Machine 2, 1 no cover 402/403/419 Accounting Machine 3, 1 no cover 519 Electric Document-Originating Machine 2 519 ditto, Principles of Operation 528 Accumulating Reproducer 548/552 Interpreters 549 Ticket Converter 550/551/552 Card Interpreters - Principles of Operation 557 Alphabetic Interpreter - Preliminary 601 Electric Multiplier - Principles of Operation 602-A Calculating Punch 604 Electronic Calculating Punch 2 650 Magnetic Drum Data-Processing Machine 654 Auxiliary Alphabetic Unit CUSTOMER ENGINEERING REFERENCE MANUALS 602-A Calculating Punch - w/wiring diagram 77/85/87/89 Collators 402/403/419 Accounting Machine w/wiring diagram 24 Base 24/26/27/28/46/47/56/65/66/526/534/536/824/826/834/836, Wiring diagrams for 024 and 056 only Also, some interesting pamphlets about system design, procedures & control with these machines and I'll even throw in ref manuals for a Honeywell 400 and the Burroughs B200 Series (not the famous B205, but 250-280). The stack is abt 7" high, wt. abt. 10 lbs. Don't know about any others, but FWIW, I see there's a 604 manual at: http://www.spies.com/~aek/pdf/ibm/604_OperMan.pdf What I'd like to do to save time & trouble is ship it all to Norm since he generously offered to scan it, and then you can sort out who needs and gets what. mike/ccs
