More AliExpress Re-Marked Chips Frustration (EPROMs & 6809 / 6309 CPUs)

Join me as I describe my frustration with AliExpress sourced, incorrectly re-marked / re-labelled, IC parts. This seems to be an ongoing issue, particularly with the retro chips keenly sourced by retro enthusiast makers.

Firstly, I was already being regularly frustrated by wrongly marked EPROM chips, which I order relatively frequently.

Then, most recently, I have been frustrated trying to source some retro 6809 / 6309 CPU chips.

During this journey I also build a couple of the 8-Bit Museum's useful CPU NOP testers, allowing me to quickly demonstrate & prove that the CPU chips I received are wrongly marked. I also include a couple of technical observations about these useful NOP testers.

I hope you enjoy sharing my journey. Let me know your own experiences with incorrectly re-marked / re-labelled retro computer chips, in the comments below.

I'm also keen to hear if anyone has managed to find a reliable supplier of correct Internal Clock HD63C09P chips!
