自制51编程器 I have build my own programmer. This device can program the AT89C51 and works with it. So it can easily be adapted to programming other devices by itself. The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 devices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed devices if you must develop with EPROM devices (e.g. Phillips 87C751).
