Analog meters

[parkan]

I remember I saw a link to an analog voltmeter for vcore, connects through serial port. I think it was on slashdot but I can't remember. Does anyone know where to get one of those?

I don't think I have seen what you are describing. There was a post a while ago that discussed a "speedometer" that showed processor usage. It connected to the serial port, but as I recall it was very expensive, over $100.
Connecting a voltmeter to the pins of the processor should not be hard, if you know which pins.
