I thought he had changed his mind about this? When I
first talked to him
he seemed pretty paranoid, but I think he eventually realized that there's
not a big enough market for there to be even a point in stealing his idea
and competing with him (although, I sure hope he's done a PCI version by
the time ISA slots disappear entirely). I certainly remember that he
softened his position about this, but I don't know if that turned into a
manual. Then again, the CW/ISA board comes with no manual anyway!
Anyway I sorted out a lot of the Catweasel/ISA details,
from disassembly and
the few sources that were available when I was doing it, it might be enough
to write a driver (I've gotten stuck with my own work on RX01 and RX23 style
drivers, I can read data enough of the time to think I'm really close but it
works less than half the time).
Here's what I've worked out on the I/O ports
(default base is 320h):
Oh, i might try some of this info I have a catweasel, sitting in my amiga
thoug. I would love to find a way to access the wierd 1mb format of the
old cbm 8250 drive.
