im starting work on schematics for building an expansion board with zorro2 slots
Good luck with that. Zorro2 should be possible (the A500 expansion port has most of the required signals, rest can be wired from the mobo directly). You still need to know what you're doing, though.
Is it possible to have PCI slots
It is not possible in any sensible way. You'd also be responsible for writing all the controlling software and drivers.
sorry im a complete noob
That combined with the "im starting work on schematics for building an expansion board" is recipe for trouble, I'm afraid.
