Hazeltine 'computer'?

[Richard]

A guy on ebay is selling something that looks suspiciously like the
monitor portion of a terminal, but he is calling it a Hazeltine
'computer'.  I asked him if it was a terminal and he responded saying:

    "Its a computer, not a monitor."

Either he didn't understand my question (I didn't ask if it was a
monitor, I asked if it was a terminal) or he had a brain-fart and
typed "monitor" instead of terminal in his reply.

The item is #300053801044 and has a detail photo of the model plate
where it says model 1DTD155463.  On the lower left rear is what looks
suspiciously like two DB-25 style connectors, presumably one for the
host and one for a printer.

So, did Hazeltine ever make a computer or did they only make terminals?
