So what the heck did I just pick up?

I have something from the same company that sounds like it might be the same
type of device. It is an

    RS-670 40 MHz Digital Word Generator.

Mine is obviously a decade or two newer. It includes a small CRT plus
keypad/keyboard and is a general purpose computer. It includes 32 output lines
(plus some misc) and the user can enter a program, either via floppy or by
manual entry on the front panel. That program is played back over the output
lines like a digital function generator.

If you find any caches of manuals for Interface Technologies equipment, let me
know. I don't have a manual for mine.
