This one is probably a long shot, but wondering if anyone has any
documentation for a Mohawk Data Sciences model 2166 paper tape reader.
The unit I have is s/n 2047 and was built by Mohawk, Montvale NJ probably
in the early to mid 70's. It's an all mechanical reader with 24VDC
solonoid and ratchet that advances the tape.
It came out of a Control Data maintanance console for the Star-100, which
sadly, as a kid, I parted out. All I have left is the cool aluminum
suitcase that it was built in... and this paper tape reader.

The maintenance console, not the Star-100, right? That'd be a big
job even for an ambitious kid.
All I can say is that I remember the suitcase tape readers; they were
used to load code onto the drum of the MCU; they may have also been
used to load CPU microcode. They probably also had uses for running
diagnostic code on the stations.
They were also used for doing things like loading up firmware on tape
controllers and the like in non-Star applications. I'd be surprised
if any documentation survived on them, but maybe some CE squirreled
some away.
Cheers,
Chuck

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.
