Re: Tapeout question for the older IC designers around here

Not so?

I recently asked Bob Pease about this very thing. I suspected
"tapeout" referred back to the old rubylith layout method.

He went and asked some real old-time IC designers.

They say "tapeout" referred to the magnetic tape, not the rubylith.

Another myth busted.
