This is also why I am a bit surprised to see it implemented in a 100%
fdc compatible fashion, since that would seem to limit use to a 3 or 4
floppy images per card, simply due to the nature of the beast..  not a
big deal given how cheap they are.  or maybe some sort of way to do a
redirect using switches, secret pokes, etc and point to different
places on the card, but that adds a fair bit of complexity.  Anyway,
Gary will do it well, that much I am sure.

Not sure when it will be finished. It depends on how much time I have over the holidays to work on it. The code is almost finished and I have started the debug process. So, look for it sometime in January 2012.
