I built the CAT interface that's in the '96 Callbook. It works well with
the FT-900 as long as you add a 4.7k pull down resistor to the Serial Out
line coming from the FT-900. I am not sure which line the Yaesu CAT
interface uses for the PTT line on the FT-900 CAT port but CT allows you a
limited amount of choices for the CW key line (DTS, CTS ??). If any of
these match with the PTT line, it should work.
If you're interested in a FT-900 control program that runs under Windows,
let me know. I am in the process of writing one. To date I have about 80%
of the available functions implemented including real-time display of both
VFO's and an S/PO meter.
