so am I (of course).  I've taken a copy over to my devl area - and I will
figure out how to include it into the next stage of dmasound devl soon.

well, I have a storage scope (which would possibly do it) [I don't run to a
logic analyser]

- but more fundamental problem - no iBook - if someone in the UK (unless
someone from elsewhere is prepared to ship one) wants to lend one - I'll see
what I can do... it's not a machine I can justify buying at the moment.

[my test set is G3/Beige, Lombard, 9600/233, and, when I get the disk
re-partitioned G4/500].

ciao,
Iain.
