SPI board

[Stephen Willcock]

Hey folks

I've been plugging away on a personal project for a while, and have just built a prototype TTL SPI board so I can hook up an Adafruit TFT / RA8875 controller to my Z80 project.

I also have my first RC2014 kit ready to assemble, and it occurred to me that I could adapt my SPI board to use with it - and therefore be able to plug in a 800x480 TFT to a RC2014 system. Actually, on reflection I quite like the idea of dropping the Mini II into my combined keyboard / SPI / GPIO setup, just replacing my SBC with the Mini.

But would there be any wider interest in an SPI board for the RC2014 - or are there other better paths to adding a TFT (or SPI for that matter) that people have used? I guess a Pico would be a more pragmatic solution, but I have enjoyed wrestling with shift registers :-)
