Re: AP-67 82C37 Application Note


Hans "HT-Lab" asked:

Hi all,

Does anybody have, or know were I can find a copy of the AP-67
application note . I googled for a few hours but failed to find it.

This appsnote describes how to interface an 82C37 DMA controller to
an 8086.

IIRC I once saw it in the appendix of one of the Intel books (~1979).
This books will not be available anymore, but Intel may have 'AN-67'
(they called it "AN-.." rather than 'AP') in their archive.

I am particular interested in how to add a page register for
the memory-to-memory transfer option,

I'd add one (three for 32 bit) HC374 or similar to it.
