I found some interresting PDFs today. AS2000 and AS2100 are indeed
identical from the architecture. The AS2000 can take max 2 CPUs and 1 GB
RAM (two memory cards). The AS2100 can take up to 4 CPUs and 2 GB RAM as
it has 7 slots for RAM / CPU cards. The CPU cards are the same, the
memory cards are different.=20

I am an idiot. ;-)
I tried to boot the NetBSD kernel directly from SRM. (This works well on
OFW PReP machines...) Now, that I used netboot:=20

OK. Now I need an additional CPU board and 24 additional 16 MB SIMMs to
max the machine out. ;-)=20
