This week, a completely wireless (emulated) 6502, here showing an ASCII art portrait of Woz. It's displayed by an Apple 1 emulator by Hrvoje Čavrak, running on a tiny cheap ESP8266 board. For input, you telnet in over wifi, and for output tune your TV to PAL channel 4 - the homebrew RF output is squeezed out as cunningly crafted digital audio on I2S. For file save and load, there's a built-in TFTP server.
It's all open source too, see
