Digging thru my junk box, I stumbled upon an old Inmac gizmo:

SP-64
Serial-To-Parallel Converter
and 64K Buffer
Product No.
8149-1

It's got a coax power jack, and no indication of what voltage polarity
it wants. There's also a 8 position DIP switch inside (probably for
setting serial parameters).

Before just tossing it, I figured I'd ask if anybody knew anything
about it. If I could get the info, I could actually use it with some
other equally ancient gear (like actual *terminals*).
