Justin, I came about your mail on an archive-server. Did you resolve your problem with the keyboard ? I think you do have a LK401, but not a Digital/Compaq one but one from Tektronix. Today I got a request from a customer looking for that Tektronics keyboard. But I only have DEC Keyboards. DEC LK401 has alway a 4pin RJ11 connector. I never came across that Tektronics keyboard before and your Mail was the only one stating the Tektronics pratnumber, which is different fron the DEC one. BTW, the serial# is different, too. The DEC ser# is longer. The TEK ser# has only 5 digits while DEC ser# have 10 digits. Sincerely, Michael
