Default Re: Ortonview PCB

I've just tried manually 'slugging' another capacitor across the existing 220pF - the MK14 keeps running, albeit still with a lot of noise on the displays, and I can step through addresses with the 'Mem' key. However the addresses sometimes increase in large steps by themselves each time I press 'Mem'. I think there's still a chance that the right delay could fix it, but it might have to be more precisely timed, ie, by the PIC rather than by external timing.
