[GreenKeys] IRL FSK-1000 demodulator

[Jim Haynes]

I picked up one of these at a hamfest yesterday.  Just to add to my zoo
of hardware demodulators.  Haven't tested it yet.  Found a manual online.

Now here's the curiosity.  On the back panel it's silkscreened for a
phone jack that says "video" and a DB-25S connector that says "parallel
keyboard" and a switch that says "baudot-ascii"  The baudot-ascii switch
has nothing wired to it.  The DB25 has a bunch of wires running under
the circuit board, I haven't looked yet to see if they go to anything.
And the video jack seems to have a couple of wires added by a previous
owner that go to spots on the PC board.

So I'm wondering if anybody know if IRL intended to offer a demodulator
with a video terminal built in, and if they ever in fact made such a
thing.

There's also an unlabelled toggle switch added to the front panel,
presumably by the previous owner.
