Its not a kit. :) And if you have a fast IBM compatbile, or a new one it
won't work. newer computers throw out extra high power parts on the
parallel port because they aren't needed in new computers. They just don't
drive the programmer.
Its also an issue because BIOS in new computers sometimes tries tog get in
the way and mess with things...

It does things like enables the onboard osc. So you don't have to have any
external components. Kinda like the GCX.
