[TUHS] AT&T Blit terminal plus terminal OS

[Larry McVoy]

My fond memories, if my old brain doesn't fail me, is being a TA at
the University of Wisconsin.  I shared an office with another TA,
we had one BLIT but I managed to scrounge another one.  We had a
serial line that ran from our building to the building that had 
all the vaxen, just one.

So I bread boarded some 8051's (I think that's them, they were 8 bit
computers that you could flash).  What I noticed was that all the stuff
we did was 8 bit clean, only used the lower 7.  So, 8th bit was the mux.
On was me, off was my office mate.  I programmed the 8051's and convinced
the lab (run by Paul Beebe, he still around?  Wouldn't be surprised if
he's on the list) to let me stick one in there, the other in our office,
presto!  Two BLITs and two extremely happy TA's.

I *loved* the BLIT, it was pretty much everything I wanted from a terminal,
it was like the NCD Xterminal only a decade or two sooner.  And kind of 
more cool because it worked over a serial line.

P.S. Pretty cool that I'm responding to the guy who wrote yacc.  Thanks
for that, I've gotten a lot done with lex/yacc over the years.  As have
countless other people.  Might be interesting to hear your storie about
what people have done with yacc - has anyone ever added up how many
yacc grammers there are out there?
