Some kind of IBM beam spring terminal keyboard? Similar to the 3270 below.
I know it's not exactly the same, but think it's in the ballpark.

Easier to find buyers on here. However, these are not PC-compatible and I don't think anyone has figured out an adapter yet. So they don't have much practical value, just moderate collectors value. Don't expect massive value like an IBM M15 has, as those have both collectors and practical value.

Yup.  I doubt there is any way to convert these but I'd love to be proved wrong.  Think these things were EBCDIC, not ASCII.  And the connector, possibly like the 3278 one shown below (not 100% sure, but if it has the same number of pins as yours then likely so) is nothing like the AT and PS/2 connectors shown at the bottom.  Maybe if you cut all the connections and wired in a new controller but that would be a lot of work and beyond my abilities.

That's a completely different interface than the AT.  There's absolutely no way you can connect one directly or easily to a PC.  Totally incompatible signals.  The only way is to custom build a converter box or totally new controller after deciphering the signals which will convert them to compatible USB and/or PS/2 signals.  There is no easy way about this.  No such thing as hooking it up to a game or parallel port and hoping to patch a driver.  Custom electronics (read lots of time and probably money) will be necessary to get anything to work.

How many have you got? How much would you want for one?

Nice boards!  I'm interested in one.

Hey Sam, you may have found your beam springs my friend.

I might like to get one just to open it up and see what how the beam springs are engineered.  But would depend on price since I have basically no hope that it could be actually used as a keyboard on any computers I have.

Yes, hopefully, though looks like a few other members here are also interested.
