Programmer for Electronic Handyman & AT90S1200:

All microcontrollers have to be programmed, be it by means of a 'mask' during their production, or by means of a special programmer. If you want to use just two or three microcontrollers of a certain type, then having them rnask-programmed is really out of the question, while a dedicated programmer may still be too expensive. For the Electronic Handyman described elsewhere in this issue, we present a small docking programmer which is actually an adapter for connecting to the RS232 interface on your PC. Using the software developed for the programmer, you can start programming AVR chips at assembler level.
