I have a couple images of a DigiLog TeleComputer at:
www.cs.umn.edu/~lemay/digilog
It doesnt have a manufacture date, but it was purchased by the university
on or before 1973. I have the three missing keycaps, but i suppose I
should see if i can find some replacement keys, since the posts are
broken off on 3 keys. They have a post vaguely like a phillips head
screwdriver.
