Many years ago, BYTE published a two-article series showing how to build a
simple SCSI host adapter for S-100.  The second article gave an outline of
driver software.  The host adapter was little more than a parallel port and
addressing logic, since the disk drive's control was quite autonomous.

Did anyone out there follow this up, and would it be worth re-doing? (I could
dig out the article, but my BYTEs are at home, and this was probably c.1981.)

How about a modern redux with IDE? Those drives are pretty good value now,
and the interface is probably dirt-simple.  (I'm just a simple M.E., so I
may be deluding myself here.)

BTW, anyone want to dicker for 180+ old issues of BYTE?  Includes No.1 and
most of the first 10 years, but sadly I've lost No.2 and a few others.
(List on request)  This is a genuine offer, but we're talking serious
kilograms here!  I haven't figured the best way to offer them, and I'm
afraid my attic will cave in! [;->)
