There's been a lot of interest in these models as of late. Despite the nonstandard connector, they can be made compatible with PCs by changing the cable, and installing some sort of driver to interpret the extra keys.

There's a thread here. (http://geekhack.org/showthread.php?t=6770) Different model, but same principles apply.

Seems to be missing a few keycaps.

The connector is a 4P4C (not an RJ connector.) This keyboard was used with IBM terminals.

That is an RJ (http://en.wikipedia.org/wiki/Registered_jack) connector...

From Wikipedia (http://en.wikipedia.org/w/index.php?title=4P4C&oldid=339053303):

   "RJ" stands for Registered Jack, a family of telephone connection standards. This handset connector is actually not a Registered Jack at all, since it was never intended to connect directly to the telephone service lines: RJ connects a phone to the service lines, while 4P4C connects two parts of a phone. It uses the 4P4C modular connector, which has four pins or electrical connections per connector.

If you want to drive yourself insane, read up on RJ types, standards, etc.
IIRC the 4p4c is narrower an "RJ11" but when our eyes see a small connector or jack we commonly say RJ11, when we see a large one we say RJ45 and everyone knows what we mean, though not technically correct in many cases.

Totally right...hadn't realized that. Will make an effort to stop spreading misinformation.
