How would look like a MCU with http://www.microvga.com/ or something similar ? I think for many people who are starting with embedded stuff is more than price interesting ease of use.

Perhaps check the back of the PC first - they changed over about 1998. The D25 plug on the back of a modern PC is the parallel port. Most modern PCs use D9 plugs rather than D25.

You can also leave out the led and its resistor. For programming you don't need a regulated 5V supply, so it could be run off 3 AA batteries to give an unregulated 4.5V supply. Then the 78L05 isn't needed. And if it is only being used to program then the 33uF and 0.1uF can probably go as well. You can certainly leave out the LDR and resistor.

Which parts can you leave out if you just want to use this as programming circuit? Cool project! Which parts can you leave out if you just want to use this as programming circuit?
