MicroDrive/Turbo and Z80 CP/M card [message #386216]

I installed a MicroDrive/Turbo in my //e yesterday. I wasn't able to get it working until I yanked by Z80 CP/M card. I guess this is not too surprising since the MicroDrive/Turbo uses DMA and the Z80 card also uses the DMA in order to take over the system bus.

Is there any way to have the MicroDrive/Turbo co-exist with a Z80 card, or should I just put my Z80 card in my ][+ and forget about it?

I tried turning off DMA in the MicroDrive settings and that seemed to improve things. However even with DMA disabled I can't boot a CP/M floppy, so there is not much point in keeping the Z80 card in the system at this point.

(Another reason why it is good to have more than one Apple II!)
