I've cleaned up this thread. It added no value.

One thing to note. The card has SDRAM not SRAM.

Out of curiosity (and because it was being talked about on another forum) what is the reason for having Zorro II RAM on the TF1200?

Other than the EC020 on the A1200 motherboard are there any other DMA masters that can access the Zorro II RAM address space?

Is it primarily for when Buffee is disabled and you're using the onboard 14MHz EC020?

A technological reason I'm not familiar with?

Its because it was asked for this way by Renee so that DMA might be possible from the IDE interface.

This board was created for the Buffee team so they could test it in a 1200. I've given them all the files.
