When I tried a colleague's Amiga keyboard with my Amiga and extended cable, everything worked. On closer, inspection, there are at least three release versions of the Amiga keyboard- the two newest ones seem to work with extended cables. 1) Keyboard with deeply sculpted F and J keys and a dull checkmark logo in the corner (Mine didn't even have a serial number). This type doesn't seem to work. 2) Keyboard with deeply sculpted F and J keys and a shiny checkmark logo in the corner. This type works. 3) Keyboard with raised dots on the D and K keys and a shiny check- mark logo in the corner. This type also works. I am not sure that these external features would always correspond to the internal circuitry; perhaps someone at Commodore could enlighten us as to the exact serial numbers which had the old electronics?
