Early on I created a Multi Chip Adapter for the USBTiny Programmer. As a low cost solution to programming common chips, I thought it was something missing from the community. So here it is. Able to program Tiny13 (8pin), Tiny2313 (20pin), or ATMega328s (28pin) chips.
SMTmulti requires an Atmel programmer, like USB Tiny, not included.
