Hello DigitalKeeper,
I forced 5V and nothing changed.
Pin15 Ramsey and Pin56 Gary gets the 5V after forcing too.
PowerConnector is in good condition. Measured a lot of times.
Checked area U975 and U976 now a lot of times. Measured the traces to next target. Everything looks fine :-(
MDAT Signal is "weird". But maybe I'm too dumb to configure my osciloscope correctly :-(
U975 Pin13 (MDAT) to Lisa Pin20 measured. No problems.
