Don't blame Minix... Tandy computers ARE NOT IBM compatible... I have several
programs that will not run at all on a Tandy and many others that will run but
are quite unusable with Tandy's lousy substandard keyboard.  It's probably
90% software compatible... and that's the good news... the bad news is it's
only about 10% hardware compatible!  In fact I have yet to add any hardware to
the Tandy without modifying it... and I've modified Midi Cards, Hard Disk 
controllers and an Eprom burner!

The real good news is that I've posted diffs on 3 different occassions to
patch the kernel to run on the Tandy 1000!  Unfortunately, no one else
seems to care... AST has not added those diffs to the supported version
of Minix, none of the archives carry them, and the compatibility list still
claims that the Tandy is incompatible.

If there really is any interest I can dig them up again and repost BUT
my current diffs are for 1.3d and will NOT apply properly to 1.2.

In a nutshell the WINI intterupt has to be changed to 2...
and the second intterupt mask has to be eliminated...

Both of these changes have should be #ifdef'd so that you can compile with
TANDY defined to get them.
