SSPPP (Super Simple Parrallel Port Programmer)
If you are viewing this than you probably want ot start using AVRs. The *best* way to start is using a commercial development board such as th beautiful STK500. The down side is that its cost $80...steap for most people. Another option is to build a simple Parralllel Port dongle for less than $3....this will show you how.

NOTE:The resistors are optional but they add a layer of protection to your par. port.
My Complete One:
For testing I just plugged the wires into the breadboard...but you could make a Atmel compatible 6 or 10 pin connection. This programmer is compatible with BASCOM(tested) and AVRDude (Haven't tested). For BASCOM you select "Sample Electronics Programmer".
My Experiance:
I have a built a couple of Par. Port programmers and I could never get any to work. I found this in the manual of BASCOM and since it was soooo simple I decided to build it....and it actually worked.I , myself, don't like LPT programmers at all...they're slow, can destroy your LPT port and worst of all I can't use it with Mac...that is why I have an STK500 aand a ATAVRISP. IF you are starting off I would reccomend you build the Parrallel port programmer just so you can flash a AT90s2313/ATtiny2313 with the AVR910 firmware. That would turn a 2313 into a fast serial port, AVRStudio compatible programmer and you can use it with Mac if you use AVRDude!!!!
