Yeah, this pattern is not so uncommon :-(((((((.
However, it might be interesting that Wolfgang
<email@example.com>, who is working at a driver for the
Miro/Pinnacle DC1 framegrabber card and who has to entirely rely
on reverse engineering under Windoze is about to build a
hardware tracer card for tracing selected adresses on the bus.
AFAIK it is for the ISA bus right now - so to use it best use a
plug in paralell port interface.
At the moment he is about to build the prototype. As soon as the
prototype works the design will be made available publicly under
I STRONGLY recommend contacting him and telling him about your
needs - this way your input can be put into his design (right
now or in the next release).
Anyway, thanks for the tremendous amounts of good work you did.
I also rely heavily on some of your drivers. Please keep on
