I recently bought a Tang Nano 20K FPGA board, due to my interest being piqued by the Nanomig project. This is the work of Till Harbaum (creator of the MiST project more than a decade ago), and combines this tiny FPGA board with a supporting microcontroller to create what may currently be the tiniest Amiga recreation in existence.

[If you’re looking for the tl;dr – the Gowin GW2AR-18 FPGA on the Tang Nano 20K features a built-in JTAG primitive called GW_JTAG, and the two user IR Scan codes are 0x42 and 0x43.]
