The story I heard is that the original SS2k-PC was temporarily
pulled from the US market because it couldn't pass FCC Class-B
RF noise certification as a computer peripheral because the
ribbon cable connector and wiring between the handset and the
motors radiated too much RF noise. Vixen's solution was to
remove the RS-232 connector from the handsets destined for the
US market, thus eliminating the need to pass FCC Class-B
certification.

I have discovered that if you add the Mini-DIN connector and
two SMT 220 ohm resistors to an SS2K, you can turn it back
into an SS2k-PC.
