> ARM Cortex-M

I almost did a prank post when Apple came out with/announced the M1. I had recently had tore down my broken PSVR which has the very nicely stamped ARM M1 in it. I wanted to post something like "Apple didn't invent it, Sony did!" Regretfully, I did not.

I don't think that's correct. The Cortex-M1 is an soft-core-only design; there's no hardware implementation. (And moreover, the ARM cores used aren't usually part of the external markings on a chip.)

What chip were you looking at? I don't see anything which looks like that in the iFixit teardown: https://www.ifixit.com/Teardown/PlayStation+VR+Teardown/6934...


I was really hoping to still have the boards, or at least a picture. I could find neither.

It was a gen1 model, so it didn't look anything like those photos on that teardown.
