Jerry,
There was a s/w package available called Transporter that would probably do
what you want. But these days that seems kinda hard on a VTR. Perhaps you could
find someone to grad Flyer clips for you? Sounds like you already have the h/w
to do the job.
I have a BCD 2000a SFC board installed in my A2000/040 Toaster sys, but
actually used it very little. I never got a frame acurate deck but it does
control an old Sony 2860 Washing machine I have :^)
Maybe I'll sell you my copy of Transporter ? I've dabbled in AREXX but mostly
modifying existing scripts. What your asking for is a pretty sophisticated
script if not rather aniquated at this point.
Goodluck,
….John
