Ha!  ya..  although, we probably could have gotten at a -100 too if
we asked.  I grew up with Neil Lincoln's kids and we spent a lot of
time at ADL (Advanced Design Lab) in Arden Hills.  I later worked for
Neil at ETA. Lots of history there.  Neil of course was the architect
for Star-100, CY203, CY205 and ETA10.

I suppose.  Clearly they grabbed some off-the-shelf tape reader at the
time and put it into this box.  It's not a complicated piece of gear
and I can surely trace wires to make it work.  I just thought it would
be cool to have some authentic info on it if it still existed.

Of course I don't want to think about having torn the entire maintanence
console to pieces but, I guess I did other fun stuff with the parts
along the way.
