This is on an 8085-based system.
It looks as if some of the features of the 8237 DMA controller (like
autoinitialize) could come in very handy in a couple of situations.
Right now, there's an 8257 in there.
Other than some reprogramming, is it feasible to make this swap? Are there
any timing issues that I need to be aware of?
Cheers,
Chuck
