Every FT-1000 already has the answer to this problem: the DVS-2 port.

G4AXX has made a very nice box to interface a PC to the DVS-2 port:

The PC side of the interface plugs into the sound card, and also into 
the COM port that controls the rig.  It should work with any contest 
software that uses the "normal" COM-port output pins for PTT and CW 
keying.

The rig side of the interface plugs into the CAT port and key jack 
(which work as normal) and the DVS-2 port. The interface switches the 
control lines on the DVS-2 connector, so it can use the audio routeing 
facilities built into the FT-1000.

Your mic stays in the front of the radio, where it's meant to be. When 
the sound card is playing recorded audio, the mic is dead so you can 
safely cough, sneeze and slurp coffee. To record to the sound card, just 
flip the REC switch on the interface, press the PTT and talk - and the 
radio won't transmit. If you want, you can also stream the received 
audio to the sound card for recording - automatically interrupted when 
you press the PTT.
