Hmmm i have a Zip GSX 1.0.1 that i doesn't have any logic chips on but
i had the sockets fitted and when putting the chips on the system
wouldnt boot. I wonder if i am missing some components for the ICs to
work...as i don't have the caps or resisters near the Logic chip
sockets...I have the transistor though
