I was thinking a simple current to voltage adaptor, maybe 2 resistors
and a transistor that worked and somebody had actually built. I'm sure I
have some optoisolators, and I've seen the stuff on the net.
I was even thinking about a one resistor e-i converter. I've got 3 days
to play with it, I might
end up building the full monty if I can sort through all the junk and
find the parts.
