Although some minor changes may be required to correct mistakes and/or to finish things I'm still working out such as how to derive the PBI right channel audio-in pass-thru... this is the design that will be built.
As I mentioned at the beginning of this topic, this project has been in the works for over a year, and I've had a lot of time to think about what it will be. What I wanted from the get go was a very compact Atari 8-bit computer that was still based on the original LSI chips for maximum compatibility (not FPGA or emulation in a Raspberry Pi). At the same time I wanted something that integrated the upgrades that gave the most bang for the buck. Or in other words, made the most sense to have in a daily driver either for general computing use or game playing. And with a multitude of SSD cartridge based solutions available supporting CF, SD, and microSD that would be my hard drive option so to speak, and not be made an integral part of my motherboard design. A 65816 was considered, but primarily I didn't feel like I could personally do that justice, and also didn't see that as required for what this project was about. And in order to keep the 'compact' aspect of the design intact while still allowing for potential expansion, a parallel bus interface was included.
So hopefully this paints a better picture of what this project is about.
Yes some connection methods have changed, specifically the SIO (D-Sub 15) and the PBI (50 pin header). But these are still very workable in their new forms, with simple adapter cables making the transition.
