May need some input from @arkadiusz.makarenko..

I'm thinking a bit of up front design for the keyboard this time...

The Keyboard on the MSX is basically 16 x 8 bit rows... if we have the CPLD specifiy the row on port C then put the data on port B and strobe a line. The CPLD can hold the data i think.

I'm also going to wire up pin 21 to the audio line incase we find a way to do SCC in the ARM.

Its like an early wavetable with predefined sounds. There will be emulations available.

Fascinating chip. It is sound chip and data mapper.
It sounds great as well.

I've made the changes for the Rev1. I want to verify the changes for the RGB connector. Right now i have it working on the CPC+ (Plus version) cable which i think i should switch to the Spectrum RGB.
