I removed the other cards because I didnt need them (stuff like serial and parallel interfaces) and was thinking of selling them on ebay. That makes me kind of skeptical that the 8MB Zorro RAM card means you can't use any other Zorro cards.
Well, an interface card will probably only take 64kb address space and no additional RAM out of the memory map.
I think what countzero is aiming at is he is thinking that the Z2 RAM on the 2386 is conflicting with the Z2 RAM on your 8MB board. I'd say he's probably right, as there is only one 8MB RAM window on the Z2 bus. If you added another Z2 RAM card, you'd be in the same boat. (You can't just add 2 Z2 8MB RAM cards to get 16MB. doesn't work that way.)
Now, why the Amiga used to boot, and then later didn't that I'm not sure about... But a bus memory conflict could cause random reboots/crashes.
(HAH! and countzero edited his response and beat me to exactly what he was saying! :lol: that'll teach me for trying to speak on someone's behalf!)
