The PGA2350 from Pimoroni is a really nice board that I've tested some time now.

The fully emulated PZ1 project compiled with hardly any changes, and can even utilize the PSRAM with very little speed loss. Nice!

This is my next step, a 65C02 and PGA2350 in one solution, almost ready to test. I'm excited to see how fast it will run now that all the pins are non-multiplexed.
