A web site that is dedicated exclusively to the 8052 mirocontroller, related products (both hardware and software), and 8052 derivative chips. (wayback version as site is shutdown)
This includes the traditional 8052, 8051, 8032, and 8031 along with more modern derivatives such as the Atmel AT89S8252, and many derivatives by Silicon Laboratories, Philips, and many others.

If built and tested programmer properly setup for your PC, you can program a wide range of tested chips from many different manufacturers easy, reliable and fast. With adapters dip 42, dip 40, plcc 32, tsop 32, 40, 48, psop 44 package chips are also supported, the 4.0 and 4.5 board programmers have adapters on board to make it even more convenient. Building it with a factory made board or a kit is not difficult if you have some experience with electronics. The software is easy to use and has all the functions you need.
An open source USB programmer for PIC micros, I2C EEPROMs, some ATMEL micros, generic I2C/SPI devices and (soon) other devices.
"After searching a while I couldn't find an USB programmer which was at the same time functional, free, and open source, so I decided to design one. Open source means that all sources and schematics are given free of charge with the rights to modify and release them." - Alberto Maccioni
These are high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
