Try to find the Sept. - Oct. 1988 issue of Micro Cornucopia (#43).  It has
an article called "Delving Into The Black Arts: Build A PC Adapter Card In
An Hour, Or So", and they mean it!  I have used the information in this 
article to build several XT cards which have worked great.  The article was
written by Bruce Eckel, who sells a book of his interface designs with a 
disk of the required software.  Your local college library should have back
issues.

If you can't find back issues locally (unfortunately, it's out of print),
you can try to contact Mr. Eckel directly at
