I would risk Centsible if I was confident that the Super DMAC rev 2 was compatible with the DMAC rev 2. I have e-mailed them to get a part number. Though I may have found someone who has one in his "shed". Waiting for an e-mail back.

I have had a look at the old EPROM (2764) and the new EPROM (27256) and they are virtually pin identical. Main difference is two additional address inpputs on the new one (27256).

Spoke to someone who used to have a Guru-ROM and they said there was an IC on the bottom of the adapter. Obviously to handle the difference in address lines. If I could find out what the IC was I confident I could make a new Guru-ROM now.
