My friend Ken, a very successful and competent professional engineer said: ______________________ Russell, I have around 20 shelf-metres of data books and while I use web-based documentation extensively for design I won't be tossing out the paper stuff anytime soon. A quick scan of the shelves for older items shows: Motorola Semiconductor Library Series A (3 volumes + index) dated 1974 Intel MCS-80/85 Family Users Manual dated 1978 HP Opto-electronic Designers Catalog dated 1980 RCA Power Transistors and Power Hybrid Circuits dated 1973 Nat Semi Logic Databook dated 1984 Motorola Semiconductor Power Circuits Handbook - First Edition dated November 1968 Many are much newer :-) Regards, Ken Mardle -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
