Can you test a CPU with a handful of spare parts?

Big thanks to https://www.pcbway.com for sponsoring this video. I bought a batch of 6507 microprocessors from China for another project. But do they work? How can I test them? The 6507 is well known for being used in the Atari 2600, but I don't have one, so I need to think of another way to test them. A technique I've used before on the Commodore 64 and VIC-20 is the 'NOP Tester'. Essentially this is a ROM replacement that hardwires the data bus to 'NOP', which moves the CPU to the next address. This will cycle through every address, which can be measured. Sure it's a quick and dirty test, and in no way comprehensive. But can I build a NOP tester and test this batch of 6507s? Let's find out... If you'd like to help support this channel, please check out my Patreon. You can also make a one-off donation or use the channel Super Thanks.
