That's a great question if you're asking about using it on Venus. Copper melts at 1084 C, so you're good there for springs, conductors and contacts. You'd need insulation for wires and circuit boards: something like fiberglass weave would be good up to 537C. No solder, wire wrap, steel posts. Resistors and capacitors for RC circuits should be similar, carbon is good and capacitors are insulator/conductor layers. I suspect making a temperature controlled oscillator will be very hard. This means power supply AC current might be hard to make. Anyway rebuilding OP's computer that can run in your kitchen oven would be a nice hobby goal. https://www.mcmaster.com/high-temperature-insulation/fiberglass-high-temperature-sleeving/ https://www.mcmaster.com/high-temperature-insulation/fibergl...
