I may actually have a printer to go with it. A BIG thing, not
heavy but taking up precious space if I put it into my
basement.
We used to use an LP25 on our DMF32 (Unibus ancestor of the DMB32). It
was a Dataproduct printer with a DEC badge. I do recall seeing a simple
circuit somewhere involving an inverter or two to attach a Centronics
printer to an LPV11. It shouldn't be a complicated matter to examine
which signals on the DP port are low-true and which ones are low-true
on a "Centronics" port and deduce which handshaking lines need inverted.
I seem to remember there was a converter (sold by Black Box, IIRC), but
the chances of finding one is pretty slim. You'd be more likely to find
a printer. Building your own converter would be the easiest as Ethan
suggests.
If you can find the manual on the DMB32 it should have the pinouts for
the cable, which will make building a converter even easier.
