RevEng Posted March 4, 2021 Share Posted March 4, 2021 As most of you are likely aware, TIA wasn't the first choice for 7800 audio. Originally the 7800 Maria chip was supposed to include advanced audio within it, but that was removed when die-space was needed for other functionality. At that time GCC pivoted to in-cart audio, coupled with TIA audio. Over the years there's been some speculation as to what GCC's proposed in-cart sound chip solution would have been like, and how cost-effective it may or may-not have been to have an in-cart chip. To help nail this speculation down, I reached out to Steve Golson. (GCC chip-designer extraordinaire, and friend of the community) Steve kindly searched through his archives for all of the docs he could find, and shared them with me. (and now you) When I received these docs, I was astonished to read about Minnie. This thing was no pokey-redux. Here we have a chip capable of basic WaveTable synthesis while still keeping things lean and cost-effective. I've written a 7800 Minnie Sound Chip article over at the 7800.8bitdev.org wiki, which also contains the original GCC docs. Steve is still seeing if there's anything else he can put his hands on, so the article may be updated as time goes on. If it is, I'll post an update here. Enjoy, and feel free to ask questions here, or discuss what may have been. 19 7 Quote Link to comment Share on other sites More sharing options...
