I picked up an old Icom 701 locally and after doing some internet research I found that it was possible to mod this radio to allow computer control of some radio functions through the back panel ACC plug despite the fact this is a pre-CAT transciever! (rig manufactured c.1980)

I know that computer control is possible because my searches led me to a Youtube video done by KA6BFB demonstrating an I-701 controlled with Ham Radio Deluxe of all things!

I'm really intrigued to experiment with the possibility of doing this with this old rig that supposedly can't be supported with any kind of computer control.Any information anyone can supply would be greatly appreciated :)
