Title: Best place to clip digital probe on CPC PCB?
Post by: llopis on 18:21, 20 June 18
I just got a cheapy digital probe to help diagnose CPC problems. What's the recommended place to place the aligator clips to get +5V and GND?


I found some pins on the expansion edge connector, but I don't like it because a) it's hard to clip exactly to that pin and b) the clips scratch the surface a bit. Is there another, easier place?

Solder a couple of wires onto suitable points and use that

Alligator clips are bad for this.
Get hooks to make a connection:

And then just clip to the Z80 or the like:
