This looks like a generic Diablo 1620. I had one once, long ago, but gave
it away after I got a faster clone. IIRC, it's an 8080-based machine,
on a half- dozen or so cards in a backplane at the back.
The interface is plain RS232 (or at least it was on the one I had; I
suppose there might have been a current loop version). Speed (110, 150,
300 bps) and parity are set by the toggle switches under the top cover.
The 'form' knob determines the printer's idea of the page length, in
inches (except for the '1 line' setting, of course.) I've forgotten what
the 'clear' button does; I think it's a reset button, and you need to
press it after changing switch settings. The 'spacing' switch selects 10
or 12 characters per inch, but, via escape sequences, the head can be
moved horizontally or vertically at 1/200 inch increments, allowing for
proportional spacing and graphics.
