I obtained a surplus keyboard a while back that has the most fantastic feel and layout of any that I have experienced to date. In attempting to use it in a new construction project, however, I discoverd that it uses Hall-Effect switches. Being stationed in Germany, I have been unable to locate any information on how to build an encoder, or even the theory of operation for these little beasts. Any information on these switches would be appreciated, to include addresses of OEMs. The particular unit in question was manufactured by Microswitch, but the letter I mailed five months ago (which included a SASE) was never answered. The mail over here is slow, but I must conclude that they will not respond. I would appreciate any info, to include deep "tech talk". Have been homebrewing computers for over 8 years. Thanks in advance. Hal
