Seeking 8726 Commodore DMA controller pinouts. The web has a scarcity of information on the hardware aspect of the chip. There is plenty of info on the software operation.
Seems the chip was subcontracted out to another chip manufacurer.
Any hardware info would be appreciated.

Hi Gordon,

the MOS 8726 was used in the 1750/1764 Ram Expansion. You can find a schematic of this on http://staff.washington.edu/rrcc/uwweb/1750 .
I hop that information will help.

Good luck,
Paul

In searching DMA I found this thread. The link is mostly dead. I was able to retrieve these pages though...

Cheers,
Andy
