SN76477N

The SN76477N was a TI tone generator chip intended for video games, but, of course, found new life in modules like Blacet’s Dark Star Chaos.

Recently, it’s been used in a couple of Thomas Henry designs like the SN-Voice and the Super Controller.

BGMicro put up some stock of the chip for sale, and it’s relatively inexpensive, so I grabbed a couple. I already had one for my (as of yet unbuilt) SN-Voice, but needed another for a Super Controller board to go with it. They arrived quite fast, actually…

Note that these are the “thin body” versions of the chip, some older designs may require an adaptor if they were intended for use with the wide-body version. The Thomas Henry boards have footprints for both sizes.
