Re: Apple II II+ Mountain Comp Expansion Chassis

This doesn't sound like a "feature" to me.   IIRC Apple cards get a slot
select signal that tells them they are needed.  With all 8 cards on at the

because the Apple II bus doesn't have a bus control/negotiation protocol.

Any thoughts?

exactly my impression. The way I would design it would be, the ROM on the apple card probably "maps" each slot on the expansion unit to active when softswitched. Kind of like mapping memory areas on memory cards to memory addresses in the address space.
