PRO-95 Interface cable...
 

For my Pro-95, I use the cable for my Yaesu VR-500, and a stereo to mono
adapter. Works perfectly. Learned this on the web over a year ago. As to
pin-outs, never did figure them out. Maybe I should find my old ohm meter.

What I need now is a USB to VR-500/Pro-95. Any ideas?
