    Those stats are some reassurance at least - thanks! I got no difference in any of my APD tests - maybe my card is faulty or I’m missing some Daystar software? I’ll try out Speedometer next… or even Doom?!? :unsure:

    I found one in a Quadra 700 I picked up (25MHz). From what I can work out it does absolutely nothing - although I’ve not done exhaustive testing.

    Macintosh IIci 5V to GND resistance?

    Hi, Can I ask a favour please? Can someone with a working IIci please measure the resistance of their 5V rails to GND (e.g. the positive side of C14 to Ground). I'm trying to fix up a IIci but not sure whether the 16-20ohms I'm getting is normal for the IIci - I've seen a few posts online, but...
