Alright... MINIX looks like a lot of fun.  And I'm looking forward to
my Operating Systems class when we start studying it.  I've got the
text [bravo, Dr. Tanenbaum!], a set of MINIX 1.1 diskettes from the
professor, and have spent several days plugging the software into
various clones and "real things".

So far, everything I've plugged it into has worked, even Radio Shack's
4000 (80386-based) displays the "MINIX 1.1" header and attempted to
boot (drive with wrong select code precluded furthur testing).  But
when I ask about technical documentation, the general response is:
"Who uses that stuff?" or "Sorry, proprietary information, not
available".

I've got an EE degree with a strong CS background, can read schematics
and generally know how to push bits around at the assembly language
level.  I enjoy writing assembly language.  But where the heck does
someone new to the PC-world FIND the documentation on this stuff??

Random problem: Every machine equipped with an EGA card seemed to have
display problems, to wit: at various random times the screen would
blank.  Pressing -RETURN- until the last displayed line scrolled off
would restore the display.  Mono and CGA cards don't seem to have the
problem.  Has anyone else noticed this?  Is there a fix?

Regards,
Mark
