Should be possible to modify the ISA version of the card. The entire
interface to the Catweasel consists of one memory location. Zero
interrupts are used.
You issue it a command, it fills it's own buffer, then you read the
buffer at your own pase.
Now processing the buffer on the CoCo would be a challenge. You don't
get bytes from the Catweasel, you get timed magnetic flux transistions.
MFM or FM streams must be decoded by hand.
