at89-prog is a simple ISP programmer for AT89 microcontrollers. It was initially written for programming of AT89S8253, but never really supported that chip because I was able to configure avrdude earlier. Currently at89-prog supports AT89S52 because I had problems with avrdude configuration for that chip and I was faster to write programmer than using avrdude. Also the avrdude it quite slow because it uses byte programming mode. Now at89-prog uses page programming mode and it's much faster that avrdude, at least with simple configuration I've used.
