I beelive soem VAXen also had ECC (SECDED) RAM. And doubtless other
machines (Zilog S8000s?)
There are plenty of cases where it's worth spending more at the start to
have soemthing that works reliably, even if the PC seems to have
eliminated that idea.
Plenty of PCs support ECC RAM. Generally on the server/workstation side of things, but
I'd hardly call it uncommon.
Of course, "working reliably" does involve a lot more than just eliminating bit
errors from cosmic rays, I'll give you that one.
