How, thanks for the long text.

I didnt't saw the A4000 yet, and i dont know exactly how it is, just know that it's working fine.

Yes it has 8Mb ram, it sholf be 2+6 . Thanks for the memory Mate, i have to check, i have more them 10 simms at home, home that i have 4x 4mb simms working.

So, the memory slots on board are fast ram? are they the same type of A1200 chip ram (2mb)?
If i put extra memory by expansion will it be the same type as in A1200 expansion card?

what advantage you get my getting extra fast ram? I know it's better, sure, but will workbench use it?
for exemple what memory will whdload use? Or does he use both fast and slow? does he use first the fast ram?

The A4000 has 2 IDEs? or only one? I have an adapter for the A1200 that let me have more then 1 IDE working. I did the idefix, so that one i know how to do it :-)

zip drive? that's very interesting, i have bay for it, and they are not that expansive.

network cards, i guess a isa card should work fine... must try it.
