Oh well, I knew at the time that was a dumb thing to say.  It's
always better to do something and then say you did it.  However,
in my defense...  I just spent my second weekend at home since
November.  The first weekend was consumed getting the monitor to talk
to my OMTI SCSI to floppy/ST-506 interface.  This was prerequisite
to working on Minix.

I finally got some time to work on Minix this weekend.  Those UART's
are a pain in the arse to use -- I wasted a lot of time getting
the TTY task working.  I got the kernel running (no fs or mm yet)
but still have stubs for the SCSI driver and the page manipulation
routines.  I compiled a few test versions with some hard-wired "user"
processes.  One test checked out the TTY driver.  Another had two
processes which passed a token (really a Minix message) back and
forth.  The current token holder printed a string to the screen
and then sent the token back to the other process.  Hence, the
screen looked like

	process 1
	process 2
	process 1
	...

That's even less useful than printing pi to 10,000 places, eh?
I'm pretty sure I will not get any more time to work on Minix in the
next two weeks.  But then (here comes another soon-to-be-regretted
statement), I expect to see a Minix login after another weekend 
of work.
