For me, this caught my attention because I am currently re-doing Ben Eater's 6502 project[0]. (I'm spreading it out to more breadboards connected together with a bunch of breadboard power rails as the data and address busses, and I'm planning to add some stuff to read programs from audio once that's done. I also want to add a custom keyboard and a forth kernel. Oh yeah, and read/write SDcard blocks with SPI.)
