[QUOTE=ScottishColin;1345717]OK - 40 pin socket with pins 36-33 folded out sideways. Solder 4.7Ω resistors to each of pins 26-33.

Pins 29, 31 and 33 through individual 4.7Ω resistors to pin 1

Pins 26,27,28,30 and 32 through individual 4.7Ω resistors to pin 8

Then insert 6502 and check pin 9.

Have I got that right?

if so, how should I connect 5 individual resistors to pin 8? Just twist their ends together and insert 1 of the resistors to pin 8?

Colin.

Unless you've made some typos, I think they recommended 4k7 = 4.7kΩ resistors rather than 4.7Ω (which wouldn't really serve much purpose being that low).
Although this may not make too much difference, if just going to supply / ground and there's nothing driving to drive out from pins you're trying to pull up / down.
