I used the non-interrupt driven driver for the 1.2 release. Fixing the
interrupt driven SCSI driver for the Falcon is still an outstanding
project. It has been pushed a bit to the background a bit because I
became rather busy at work and I really wanted to turn my Hades into
a working system.
Why the interrupt driven driver does not work on all Falcons is still
a mistery to me. Cedric pointed me to the Linux sources because he
thought they had solved a simular(?) problem between their 1.x and 2.0
release, but I couldn't find anything interesting. Anyhow, I am willing
to open the case, but I surely need someone with a Falcon who is
willing to help. I just can't fix bugs that I can't reproduce.

I didn't hear about big trouble after the 1.2 release, so I guess
it's quite stable...

There are 2 problems with ser02 on the Falcon:
- You have to do a signal conversion, as there is only a
Lan connector on the back.
- The frequency parameters for the ser02 port on the Falcon
are guesses. Someone with hardware docs on the Falcon can
easily check their correctness. Maybe someone with a
'Compendium' can verify them? The tables are in atari/dev/zs.c.
