Can anyone supply me with a source for the "official" PC/AT (a.k.a. ISA) technical specifications? Hopefully this should include not only pinout info for the connector(s) but signal timing charts and relationships. Is there an IEEE spec published? Or does Big Blue have the last word? Titles, names, addresses, phone #'s would be appreciated. Bruce Miller (miller@gvlv3.gvl.unisys.com) Vacuum tubes are not dead - they just smell that way.

Yes, IEEE P996. > Or does Big Blue have the last word? No, IBM has absolutely nothing to do with this. 1/2 :-) > Titles, names, addresses, phone #'s would be appreciated. I recommend: Interfacing to the IBM Personal Computer, 2nd Edition Lewis C. Eggebrecht, (c) Sams 1990 ISBN 0-672-22722-3 for a good overview of PC/XT/AT/ISA/EISA/MicroChannel architectures, and AT Bus Design (paperback $70.00!!!) Edward Solari, (c) Annabooks 1990 ISBN 0-929392-08-6 for the real hard-core ISA details. -David Doudna doudna@nsc.nsc.com

But somebody recently published a book with timing diagrams, and I would assume it has the pinout of the bus connector as well. But, in case it doesn't you can look in IBM's "Technical Reference Personal Computer AT" PN 6280070. That book at least has the bus connector pinout. The timing stuff was recently published in a book called ... Well sorry, I can't find it right now. But I saw an ad for it in the July issue of "TECH SPECIALIST." TECH SPECIALIST is a new magazine for techies, and can be bought in B. Dalton Book stores. -- "Worship the Lord your God, and serve him only."
