I am clearing these out of my stock: 4 are beige, with no PN on the back. They have a small RJ9 type connector. 3 are missing one or more caps. 4 are dark on top, and beige on the back. There is no PN. These have the save telephone style connector. All are complete. These have not been tested

Wyse 60 keyboards work out of the box as USB with a converter sold by Orihalcon on ebay. So do all IBM terminals with an 8 pin connector or any other IBM terminal keyboard (but not beamsprings). The converters cost about $35-40 each. I use them to test all the terminal boards that I sell.
