How can I find my Apple computer purchase history?

They can't. Apple didn't sell directly to customers anywhere near that far back. Until 2001, when Apple opened their first Apple Store, Apple sold only through dealers. So no one will have a complete history of all your purchases.

Regards.

Apple started selling directly to customers online on November 10, 1997 – before there were retail Apple Stores. This was a couple of months after Apple bought out the key assets of Mac clone maker Power Computing, which had been selling clones online.

not sure if that is info they keep track of, think in many countries it would not be legal for them to

Thanks, SoC. I'd forgotten that the online Apple Store predated the retail stores by that much. But in any case, my original statement still applies; no one is going to have a full list of all Apple computers purchased back to 1984.

Regards.

Apple should have a complete list of ALL Registered computers.

I registered ALL 200+ Apple computers that I have purchased.

Trust me, they will not be able to give you a list of all the Apple systems you may have registered over the last forty years. As Rudegar said, any such records would cover millions of purchasers and hundreds of milliions of device. I very much doubt that they could even give you any list beyond what is shown in your Apple Account. But if you want to contact them and ask what they might be able to provide, you certainly can.

well they likely sold 100s of millions over the years

but you can suggest they do using their feedback channel
