[Coco] Difficulty loading CAS files - real Coco2 from PC audio out and CocoTape.exe

[Aaron Wolfe]

I don't know if CoCoTape expects .cas or .wav (if it does expect wavs
though then its essentially just a wav player?)

The Toolshed has a tool for converting .cas to wav, which could then
be played with any media player supporting wavs.
http://sourceforge.net/projects/toolshed/

If you are up for making or buying a serial cable, you can use the
bitbanger built into the coco to load .dsk a variety of ways.  It is
possible to load the coco side software for this via the cassette
port, but it's more convenient to have it in a rompak, these are not
expensive.
