[sci.electronics] Computer Interface

roybalm@tramp.colorado.edu (ROYBAL MICHAEL) (01/20/91)

	I wanted to know if someone could reference me to a location where I can pick up a schematic for circuits that I can use to interface my own projects to my IBM computer.  Or what is needed to hook connections directly up to the parallel port and/or Serial port on the back.  Thank you for any info, either leave a reply here or e-mail me.

	I am sorry for having to repost this, but it seems that some terminals
do not put a cr/lf at the end of the lines, so here is my post again!

s covering this subject would be greatly appreciated.  Pleas e-mail responses.

An excellent book is _Interfacing to the IBM Personal Computer_ by Lewis C.
Eggebrecht, published by Sams.  It covers both the PC and AT bus extensions
and includes lots of schematics.

Another source that might kill two birds at once for you is JDR Microdevices
(see back of any Byte).  They've got a board that comes complete with
circuitry for interfacing to the bus (via and I/O port, I think).  It's
around $40.00 for the PC version.

There is a good book called Interfacing to the IBM Personal Computer, or something similar, by Eggbrecht.  It comes highly recommended.

Eggbrecht was the fellow who went to a company in NJ that was planning
on cloning the Apple II.  He was on the IBM PC design team.

Sounds like a winner to me.

Regards.
