New schematic which has the edge connector rotated 180 degrees, to correspond with the layout which has to get the same correction to correspond to the original ZX81 which has pin 1 on the left hand side (bottom side for the ZX81+35)
also the edge connector clock is now a permanent 3.25 MHz instead of simply the CPU clock (which can switch from 3.25 to 6.5MHz, which is a problem for the PSG. [[Category:Pictures]]
