If it's what I think it is, I've got one in my garage, with manual. Your
basic guess is right: It fits between a terminal and modem. It has some
*very* primitive line-editing capability, basically you entered numbered
lines of data while offline and then you could upload to your timeshare
account later. This was when connections were 300 baud and remote access
was *expensive*.
I'll look for the manual when I get home. I'm pretty sure it's the same
model # as yours. The commands should be similar, anyway.
