Awesome - although I think it glosses over the origins in earlier Z80 sound drivers. | |

We used to use very similar looking ROM-RAM In-Circuit-Emulators with the same long ribbon cables at work in the early 2000's.
The things we so UNSTABLE. You would have to restart and reload the session every 1 to 2 hours. I'd imaging using one 9 to 5 every day would drive you crazy! |

I guess at lower MHz rates the stability might be better, but still even better to avoid the long ribbon... | |
