Intel PIII processor GND and voltage pins? Answered

 I am making the hot plate found at: www.instructables.com/id/Hot-Plate/

I want to find the 'voltage' and 'gnd' pins for my Pentium 3 SL4MF processor.

The datasheet at: download.intel.com/design/PentiumIII/datashts/24526408.pdfshows the pinout, but I can't figure out which pins to connect the wires to.

Please Help.

Go to page 68 (of 94 ) on the PDF you linked to. That shows you which pins are Vcc (+V) and Vss (GND), and how to read them using the grid system. Starting on page 70 (of 94), with AM22 in the right column, are the GND/Vss pin designations, ending with Z34 on page 71. Page 72 starts the core Vcc designations at  AB36 all the way down to AJ9 on page 73. There are more further down, but I'll let you find them.

I don't believe that actually works as a hotplate. I see it as an idea, nicely built, but not functional.
Apart from power you'd need a clock, and some instruction to create the switching that makes CPUs hot. Essentially you'd need it plugged into a PC to get it up to temperature.

A chip like that has DOZENS of ground (Vss) and supply (Vcc) pins !
