Is it possible to use multiple Zorro2-memorycards in the Zorro3 on my Amiga4000 or is it only possible to use one?
AFAIK there is no limitation, except that Zorro II cards will go into a limited address space. Zorro II address space is limited to 8MB between 0x200000 and 0xa00000 on Zorro III machines.
Zorro cards will always be configured to their natural boundaries, i.e. 2MB cards will always be located on 2MB boundaries.
So you can put two 4MB cards in, or one 8MB card, but not more. If other Zorro II memory cards are in (like a Picasso II), then the address space will be even more limited.
Zorro III cards will be out of the Zorro II address space and won't use it, so no need to worry.
Please note that Zorro II memory cards are slow, and sometimes cause problems in Zorro III machines (if the design is not done correctly).
