Nothing amazing to report but all the sockets are done. And, just because I had it I, installed a 74AHCU04 for the oscillator circuit and works fine. But there is some noise so may have to fiddle with the resistor values. But still want to keep it original so will try a 74LS. If it worse then I will need to accept not all of it can be original. Need a clean stable clock. The CPU is on the other side of the board.

Now onto the resistors and caps. Notice on the right? So many resistors and just to make it fun they are nearly all different values ... they are for the D to A used by the composite video out.
