I like the vacuum Idea...
Just run it under as I heat it up...
Dang... very smart...
The oven idea is pretty cool for salvaging parts,
I would be interested to know at what temperature and for how long...
:)

Try using a vacuum cleaner on the other side of the board. Just be
cautious of static electricity! The little remnants of pins and
excess solder just vanish.
And then there's Joe's method of cooking the C64 board in the oven and
bashing it to make all the chips fall off...!

Yes, I've done the same. Custom colors and message, just to personalize it.
I also put in a larger EPROM with room for four kernals and switches
on the side of the C64 connected to the EPROM's upper two address
pins. So I can switch between the standard kernal, my custom kernal,
and JiffyDOS (no fourth kernal yet).
It's neat because you can switch between them *while the 64 is
running* in most cases ;-)

You should be able to simply concatenate them and burn them together.

You should check out the cbm-hackers mailing list, it's focused on
exactly these kinds of hobby projects.
