The KimCard is a credit card sized Kim-1 emulator based on a Atmel XMEGA32.
The KIM-1 was a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976.
Revision 2 of the KimCard is using obsolete thru-hole displays and need a few patches on the back to funcion properly.
Revision 3 will be using SMD displays.
The current firmware runs the KIM-1 bios/monitor fine as well as some of the games from The First Book Of KIM-1.
