RE: Claim to faim

The DEC engineer's name was Dan and we always find him drinking a TAB and a Marlboro.

This sounds like the WATCH/FORCE duo of priv utilities that I got in
trouble over :).  I used FORCE to type what seemed like "line noise"
and spurious erase characters into a high school user's input stream.
I remember looking at the source code for this -- all these magic
PEEKs at various locations in the system area (had to be priveleged to
do that) to read the I/O buffers and POKEs at other magic locations to
insert your keyboard input into the victim's input buffers.  Now that
I think about this, is there any legitimate reason for a program like

Tangent: I remember Ron Dozier explaining how BASIC-PLUS code was
really compiled internally into "push-pop code" and that everything we
wrote in BASIC-PLUS was really executed as a stack machine.  Gee,
sounds just like Java with its virtual machine instructions derived
from C++-ish object-oriented code, huh?  The more things change, the
more they stay the same. :)

Hey!  That reminds me, what was the name of the DEC field engineer who
would periodically come down to fix our broken DECwriters?  I'm
drawing a complete blank on the guy's name, but he was friendly and
apparently had a certain fondness for DELTA.

Lots of people have mentioned Teresa Green in one way or another, but
I'm sorry to say that she draws a complete blank in my mind.  I guess
she was out of the picture by the time things moved to Willard Hall, or
I was just too unimportant to be of any concern to her?  (I have a
distinct memory of being constantly dismissed because I was "just some
kid" -- I think that's a direct quote from Uffelman!)  The only memory
I have is of Ed Jones mentioning her -- but I can't even remember what
he said or what context in which the conversation took place.
