I'm not planning to put the mux chips on unless you think thats important or would slow the software down?

I can't see the reason why. It would be literally few cycles to calculate it?

Indeed. if there are any spare pins on the CPLD i'll wire them to the ARM for future fudging.

Motivation for this design is to make it very easy to assemble. Like in about 25 mins.

EDIT: There is a new MSX section in the forum and i'd love to start MSX conversations there but please keep this topic about the TFMSX.

@arkadiusz.makarenko I've used port A and B wired to the PSG. I've also still got dual USB still wired up.

Otherwise i'm just looking for a 5v DC jack footprint

Did you move both oscillators?
I think you could drop RTC one, unless you are planning to use it somehow?

Ah good point.. i suppose its possible we'd implement it ... its not in the way... i'll leave it for now.

Amazing work so far @terriblefire. This looks like the perfect way to finally get my hands on a 2+ machine. Really looking forward to see where this project goes.

It's not that bad actually, at least from the time I've spent on msx.org. People are generally polite and helpful, but I only have experience from the English forum.

Sorry but i simply hate forums now.. with the exception of this one. I dont engage with them anymore.

I have ordered both video chips, just in case I might ever need it...

Sweet.. i've noticed one small mistake so far.
