Hi Philip,
>....Are you _sure_ it's 300 baud? I thought it was 2400....
Well, it has been a few years since I had much to do with the C64 so my
memory could be faulty. I definitely remember a figure of 300 baud quoted
somewhere in relation to storage though....perhaps that's the rate that the
cassette system runs at?
I know very little about CBMs cassette system, all my programming was
related to the disc and cartridge systems.

No kidding. I remember when systems like "NovaLoad" came along allowing
games to load from tape faster than they did from disc. And then the
floodgates opened....

Hmm, memory is hazy now, but I think cartridges like Epyx' "FastLoad" did
use a higher than normal baud rate when running in fast mode (bear in mind
that it's probably 11 years since I last used my FastLoad cart).
I only heard of this trick of using two lines on the serial bus to double
the data transfer rate quite recently. AFAIR the serial bus already uses two
data lines, one for data out of the C64 and a second for data in?
Would I be right in assuming that this trick involves using both lines as
inputs or outputs simultaneously?
