.Nm Avrprog
supports Atmel's STK500 programmer as well as a simple hard-wired
programmer connected directly to a

parallel port. In the simplest case, the hardware consists just of a
cable, connecting the respective AVR signal lines to the parallel port.

need to be connected to the parallel port. Optionally, some otherwise
unused output pins of the parallel port can be used to supply power for
the MCU part, so it is also possible to construct a passive standalone
programming device.
Some status LEDs indicating the current operating state of the
programmer can be connected, and a signal is available to control a
buffer/driver IC 74LS367 (or 74HCT367). The latter can be useful to
decouple the parallel port from the MCU when in-system programming is
used.
