[GreenKeys] TeleType 5310

[Jim Haynes]

That was way past my time, but I think it might be a dot matrix printer.

Datacap, Inc. is a small company in San Diego formed by a couple of
former Teletype engineers and I think mainly did a trailing-edge business.
That is, if you had a working Teletype Model 40 setup they could
connect some off-the-shelf printer to it.  Or they could help you
keep your old Teletype stuff running.  Looks like now they are mainly
selling line printers.    www.datacap-inc.com
