Do you know about this project? Looks so promising. I'm not the author.

This project looks really promising, with CGA, MDA, and Tandy capabilities now.
I've been trying it fully simulated on FPGA and the Tandy part is the funniest for me.
It only lacks Full Hercules support.
Wow, bringing Tandy Graphics to a PC seems to be a 35 years old dream coming true. Especially as I already have Tandy Sound in my Commodore PC20-II, this would be THE card that could replace the original ATI Graphics Solution that's in there (My EGA Wonder 800 runs awfully slow in this machine and the ATI only supports 16 colors in Plantronics, which is only supported by Planet X3 and some Sierra games with additional driver - but so, I might be able to experience the full Tandy thing on this machine).
Definetly have to watch this and buy one once market-ready.
