Quote from: kbjunkie on Today at 11:29I've already reflowed the cable on the MF2 side and removed and re-crimped the cable. No difference. It looks like some of the cables in the ribbon are broken somewhere. I think the only way to sort is to replace the cable.Will message you with what I have spare.
Do you have any parts to build the cable - the ribbon, 50 way connector on the CPC side and the solder crimp connector on the MF2 side?
Thanks,
Mark.
Quote from: Bryce on Today at 11:54the clock glitchedI tried this. My tests show that the clock is only wrong when touching the contacts with a bare hand and rubbing the wires against each other when the clock is active. there is no interference from the wires as the antenna MW radio.
a few cycles earlier. So the clock was unstable

and the entire system was in an unknown state there after.

Notice that the clock inverter gets a heavy zero at the input - it has no chance of ticking even once. The freeze is sure and strong.On the address lines there is &B100 or &B101. I use rectifier diodes so they have a 60ns propagation time, they may not stop at the first LDIR address.
