Have it since 1987 ...
Just a prototype, worked on a Dragon 32. I've reworked the sources
for Basic hooks on a CoCo, but untested so far.
I decided to use an extra PIA on the extension slot, on a Dragon 32
the parallel port would be an option too. On a CoCo (2) the parallel port
is missing, isn't it?
Support for SpeedDOS (parallel cable) or burst mode (for 1570/1571/1581
drives) is on my todo list ...

As some other mentioned, this drive's communication is aweful slow, but
the ease of random access makes it.
