> a resistor was, like today, about $0.05. Sourcing on that, for no particular reason (also, since 1965 the dollar has inflated by ~10x): Through-hole types that would have been used for this are around .5-1 cents in 5k quantities, and ~5 cents in units of 10+ (right on the money! I wouldn't have known that offhand.): https://www.digikey.com/en/products/filter/through-hole-resistors/53?s=N4IgbCBcoJYCZRAWgIwAYBMIA0IAOALojiAQJ54CmicAzgMYgC%2BTQA https://www.digikey.com/en/products/filter/through-hole-resi... SMD/chip resistors, which are used for most things except relatively small scale products, are .2-.5 cents in bulk: https://www.digikey.com/en/products/filter/chip-resistor-surface-mount/52?s=N4IgjCBcpgnAHLKoDGUBmBDANgZwKYA0IA9lANogAMIAugL73EBsyIAlgCZQgC0YVAEwhiABwAuPESHEBPUfh6dcaRkA https://www.digikey.com/en/products/filter/chip-resistor-sur... Note that obviously all these prices are pretty rough- digikey is not the cheapest source, and the context of the industry has changed a lot.
