I don't know.

IIRC what they are known for is advertising tagged queueing and/or
disconnect/reconnect but not implementing it correctly. Anyway, with
good used DCAS-34330 drives going for less than DEM 100 nowadays,
I won't bother about that Fireball any more.

This was for a temporary box, it was 3 a.m. and I wanted to go to bed.
So I took that Sparc-2 and was done.

I don't want to "limp along" ;-)

That Fireball had been retired from day-to-day use when I got my new
IBM DNES. I had to reuse it because the Fujitsu 2694 I had planned to
use for that temporary box had not survived two years of storage in
the basement and was giving hard write errors.
