I'd given up on finding ones with the /READY

I needed one to add double sided to my Canon Cat. It
had a Canon with a weird 20 pin cable that I just recently
figured out the wiring. I made a circuit with three ttl
chips to recreate the /READY that works well enough.
I had to make a cable translator anyway so I had
a piece of proto board to add the chips on.
I've done the same here with an 8-pin PIC (the advantage is that
there are no discrete timing components). The same could probably be
done with one of the 6-pin PICs. But finding drives with a native
READY signal is better.
