Speaking of the Catweasel, does anyone know what the

Just so--and the high order bit of each byte indicates if the INDEX/ line is active. The
Catweasel is exceedingly simple-minded. One might be able to get rid of the SRAM and
counter that the CW uses for track storage if the host controller supported reliable DMA.
Maybe have 115200-baud RS232 and multi-megabit USB as
an option?
Add a jumper to the board to switch between them - one position for RS232, the
other for USB.
I *like* the idea of ethernet myself. Hardly anything, save for some very vintage gear
that
doesn't understand it. I wonder if you could use one of the standard services, such
as ftp, to
nearly avoid having to write anything for the host system...
