The SST chip (and hence PCB).

Thanks for posting that presentation video link. "Very interesting" (now where is that from? Smile)

So my HP-15C purchased in March, 1982 is pre-SST. I didn't know that. However my mid 1985 HP-16C is post-SST! Both made at HP Corvalis though.

Plus the original HP-12C had a "comma bug" long before 2023! Start at 21:50 in the video.

More on the HP-12C starting at 28:20.
