Remember? I still have, operational, an Apple II which, IIRC, was a 6502 processor, though I also had (have) the optional Z80 processor board so I could run CP/M.
It's not exactly my daily go-to machine, though.
I do still use a Core 2 system, though. I'd have to go check to be sure, but I think it's a Q9550S processor. And yeah, 4GB DDR2, like a few others here.
And it still runs just about everything I need, at a perfectly acceptable speed.
Cores? 4, I 'spose.
Threads? Hah, new-fangled techy things.
