Title: bending C64's VIC-II graphics chip < yay or ney
Post by: Luka on December 22, 2007, 02:09:22 AM

it seems that sega mega drives, atari2600s, NES systems and gameboys are all the rage for bending at the moment however i have a bunch of c64's with SID chips removed lying around my house and im wondering if there is anyway i can turn this machine into a nice bent vj machine

has anyone had any experience with this?
i have checked the net and cant find too much

yay or ney?

Sometimes you just have to be the first one to do it I say Yay, expecially since they're trash now anyway.
The C64 is really primitive, that should be good. Load up something that works the graphic chip (Or write a quick Basic prog that prints coloured blocks or something) then poke around the graphics chip. Don't touch the voltage pin.
Let us now how it went.

Bear in mind that the address and data pins are shared with the CPU and memory, so shorting them will cause the CPU to crash.  Maybe trace cuts would be a better idea, although if you were feeling particularly hardcore you could remove the VIC-II completely and fit it to a daughterboard with some buffers.
