Hello,

I think you would need only WriteByteDelay, this inserts X ms
artificial delay on each byte sent.  ReadDelay is an artificial pause
when returning disk sectors, I don't think you should need it.  You
might get more acceptable performance this way, obviously still not
ideal.

It might be that a slight delay on the first byte would be enough to
let the bitbanger routine sync up.. I will add such an option in the
next version just in case.  I don't have a CoCo 1 here to test with so
my apologies, the CoCo 1 support is not well tested at all.
