@allison @mint What I want is a 500mhz 6502 that can run Apple + Commodore software w/ a DSP on the side that runs a similar standarized command-line system.
Then the DSP or main processor can talk to a GPU card which hopefully will also have a similar command-line system.
Give them variants of the same interface and try like hell to get rid of the driver interfaces. Let the GPU be the complex thang + handle both video+compute cycles everything else can be pretty simple. Nutty idea I know.
