Maybe. Although if you check how many items he/they have listed that point starts looking moot. I don't say they're used and programmed previously. I hope not. But this discussion made me take a closer look at them today. They definitely look suspicious on the outside - partially (not completely) similar to what the Chinese do with recovered chips. But… The "MaxLoader" says they're blank.

When I read the device, they _all_ read as "0", yet when blank-checking it is supposedly "blank" - so aren't they programmed the other way as e. g. EPROMs?

Do you use the USB variant? Does the latest (6.xy) software work for you?

Could you send me the programming file you used to program working C64PLA into them?
