Cores That Don’t Count

Today's computer chips are so advanced, they are more 'mercurial' than precise – and here's the proof
Rarely seen miscalculations now crop up frequently at cloud hyperscale
Loved the last paragraph of the article:

"In our recent experience, roughly half of these human identified suspects are actually proven, on deeper investigation, to be mercurial cores – we must extract 'confessions' via further testing (often after first developing a new automatable test)," Google's researchers explain. "The other half is a mix of false accusations and limited reproducibility."

While cleaning up some old stuff I found my old 368 (original Compaq Deskpro 386) that didn't count or run 32-bit software.

I think the one on the left has the bug.
The 386 on the right has the double sigma mark to it's been tested for 32-bit operation.

There are three distinct species:
- no marks
- "16 bit s/w only"
- double sigma
