Built a 75MHz 65c02 on Nano20k
https://tildegit.org/potato/TangNano20K-65c02-experiments
A nice potato! 60MHz (now 75 MHz) 65c02 CPU, 64KBRAM, UART. SD card an 8GB SDRAM for RAMdisk.
EHBASIC, WozMon, VTL (a 1KB tiny basic-like language).
I should get FigForth working next, I suppose. (Done!)
Uses 6% of available logic (and 2/3 of the Block RAMs for 64K)

Got the SD card interface working, at least reading random sectors.

Reading files from FAT32 and FAT16 formatted drives. I never got this far with SD cards before.
