HHC2021 Bob's Calculator Challenge

[KimH]

I had 2 - #1 (odd one to know) and the long list of “unused” model-numbers, 44 was what got my attention there.

On the shortest lifespan, I had 28C - I recall it was about 12 months between the C and the S. Can’t find a list anywhere with intro- and obsoletion dates. I am sure one exist, but don’t know where.

Fun video to play along with, thanks Bob!
