It wasn't the Deneb that caused me issues.
The Deneb worked fine on both machines, but I don't remember trying it with the zorram.
Wouldn't the big trick to run with both? AFAIK the issue is mainly with Zorro3 bus master cards and bugs in the Buster that give issues when multiple bus masters are present. I recall this causing compatibility issues and that Buster11 was the best chip (but not error free)...
Methinks Deneb runs in Z3 bus master mode...
