prog89S52 is a utility for Linux on the PC, allowing programming of Atmel's AT89S52 microcontroller via the parallel printer port. Atmel's 89S are programmable via an SPI port and therefore require absolutely no additional components in order to program them in-system.
This program requires a standard "Centronics" type PC parallel port (a bidirectional, EPP or ECP port is not required). A 5-way cable is required to connect the microcontroller to the port; wiring information is given in the included manual page.
Remember that a clock source is required in order to program the device, and that EA must be tied to Vcc when programming the internal flash memory.
Note that since prog89S52 uses ioperm() and friends to access the underlying port hardware, you may need to run it as root.
Both binary and source may be freely distributed and modified, but both are provided without any form of express or implied warranty.
