Retrowiz uPC mainboard 1.0

I fixed bugs from the initial version (inverted PS/2 connector, fixed SD card part layout, rearranged the connectors) and now RetroWiz mainboard "alpha" version is assembled and tested. Please download the Eagle files below.

Several hand-assembled boards are also available on Ebay, see Store

How to program the mainboard

Use any AVR ISP programmer to download the program through ISP connector (MISO, MOSI, SCK, RESET, GND). I prefer an old AVRISP MKII from Atmel or ZeptoProg. All of them will work.
