I bought an IBM 93Y1231 CANPOS (Point-Of-Sale) keyboard super cheap on fleabay. Its branded IBM but was actually manufactured by Toshiba. I bought it because it has tons of programmable (?) function keys. Except I can't find the software to program them! I found some obscure references in some IBM service manuals that refer to a "CANPOS keyboard utility" but I cannot find it anywhere. Can anyone help me obtain a copy?
