I am selling a keyboard, which I believe is for a IBM 3270 Terminal. This is obviously just a collectors item, I have no idea if it works and sold as broken on this basis.
I would like 300 euros + postage for this. It's pretty heavy, and I need to weigh it to determine the cost. Payment by PayPal. Offered elsewhere too...
For reference here are some other pics and links

http://www-03.ibm.com/ibm/history/exhibits/dpd50/dpd50_chronology4.htmlAccording to this IBM announced the 3270 series (complete with the 3277 terminal which used the pictured keyboard) a few weeks before those patents were filed, with demonstrations come not long after. Now, IBM being IBM, that sort of stuff wouldn't have come out of thin air, so the Beam Spring probably dates back to the late 1960s. It's certainly a half way house between a typewriter mechanism and a modern keyboard switch...
