Gee, I've been doing this all wrong; I offered several boxes of data & related books for free, but had no replies at all - just found a box that I overlooked when I tossed 'em out, so let me try adding a handling charge & offer them for $4.95 ea. & shipping :) Zilog Microcomputer Components Data Book Feb 1980 Intel Microcomputer Systems Data Book 1976 (SBC's &c) Intel Component Data Catalog 1980 Intel 8048 Family Applications Handbook Jan 1980 (Apps & Assembler listings) Intel 8080 Microcomputer Systems User's Manual Sep 1975 (Apps & data sheets) Rockwell Electronics Devices data catalog 1981 (AIM65, RM65, System65, R68000, PPS-4/1, modems &c AIM65 4 Manual sets: User, Programming, Chipset & Monitor Listing The Elementary Apple 1983, Wm. B. Sanders (Datamost) (Beginners's User/Programming) And some Mostek & Synertek sheets as well; they were mostly into F8's and Z80's; you're probably thinking of MOS Technology for the 6502, and I just happen to have the MOS Microcomputers Programming Manual so after you get your $5.00, just send me 4.95 <g> m -------------------Original Message------------------ Date: Sun, 28 Oct 2001 23:18:47 -0800 From: Mike Ford &lt;mikeford(a)socal.rr.com&gt; Subject: A couple old books, 6502 and Mostek I found a couple books while digging in boxes at TRW. Beyond Games: Systems Software for your 6502 Personal Computer. Ken Skier This is a very early book, copyright 1981, covering a series of articles assembler, text, printing etc., but with a very basic approach, and over half the book are reference listings etc. Has a few specifics for each of Pet, Apple, Atari, and other 6502 computers. Mostek, MOS Integrated Circuit Guide. Magazine sized, 138 page, blue and silver book, copyright is 1975, but the only microprocess it mentions is the F8, and I was expecting 6502. Covers several early memory chips and some consumer calculator chips, very nice condition. I am thinking about $5 for either book, but best offer and postage gets it.
