Well, unfortunately it appears I was sent a defective STM32F303.
I removed it and put the original F072 back and my Nano is working again.
I thought I might have a problem when I saw that the seller had wrapped shipping tape around the chip carrier to hold the F303 in place. So much for no antistatic precautions.
I'll have to see if the seller will send me a replacement, wrapped in aluminum foil.

Try this early test version, it can run on F303 without external crystal, there may be a lot of errors.
