Mr. IBM local dealer is correct in that it is different, but "scan" is the term I'd expect from a car salesoid... (insert your favorite flame here) The keyboards are not interchangable. They communicate with the computer with a serial protocol a whole lot like that of the "COM" ports. Except there is a different number of bits used on them. If U want to know more about it, there is a nice discussion of how they work in one of the 1990 issues of "Circuit Cellar" (I think it was around April). I would think that if one exists, one of the Digi-key/Jameco type places (that advertise in the back of BYTE) would probably have one. !
