Zilog Z8530, there are 6 and 8 MHz version boards, mine belongs to the
latter.  This chip is also used in SUN3/50s and SUN3/60s.
It *should* be possible to sort of take the SUN device driver for NetBSD
and change it with minor fuzz, provided that you know what you are
doing.. :-)
But I do not know how to get the address from the Zorro bus, nor how I 
interface it among the other Amiga device drivers.

How do I find product-id?  (That is for the board, right?)
ASDG made this board, if that helps with the manufacturer id...

I have an A3000 running NetBSD 1.0, slighty patched to get rid of the
worst bugs.  I am prepared to invest time in getting it running with
this serial board, but I need some help getting started.. :-(


Use MS-Windows every morning and nothing worse will happen to you all day.
