Default Mini-scamp microcomputers

While there is such interest in switches and LEDs style of SC/MP microcomputers, I thought I'd show off these little gadgets I built about a decade ago.

They use an 18 pin PIC and have a simple, non-realtime SC/MP emulation. The 'memory' is the PIC's non-volatile memory and is pre-loaded with the Mk14 'Square root' program when the device is programmed. I used something like charlieplexing to drive all the LEDs. It executes slowly so that you can see the LEDs blinking. On completion of the program the 'HALT' LED comes on and the computer stops. You can then peek about the memory to see results, etc.

It's meant to be a kind of executive toy, I suppose.
