I recall the Bell 300 modem (non-acoustic coupled). It had a AT&T Bell logo
on the front. So either Commsphere or Dataphone, probably Dataphone. I think
it had 103 on the front. Black plastic front, rest of it was metal and an
external 48v DC power brick, 2 screws on the brick. I can't recall if the
modem had screws or was hard wired. I do recall a DB25, male I think.
