probably tell

I think the only wafer's I've seen out in the wild are some wafers
from Tektronix. Back in the 70's when I was in
school someone from
Tektronix visited us, and everyone got a wafer in a little
plastic
wafer holder. I know I've still got mine, I'm just not sure where
it's at, it's all of about 2 1/2".
