I'm starting to doubt myself now, as I'm sure you are...

#158
IC in breadboard
Black pin7->red pin 8 UG5 - 1.50Ω
IC in socket on motherboard power off
Black pin7->red pin 8 UG5 - 1.21Ω

#159
I cannot get a reading on the old meter set at 200 Ω. At 2MΩ I get a solid reading of 1.05

With regard to pins 9/10/11 of the 6502, please can you tell me where the black probe should be?

Does any of this make any sense to you?

Your help and patience is massively appreciated.
