Holly: Amen Submitter! These belong in a museum! They are absolutely useless in a public library. Remember this post? And this one? We’ve had a few examples of old time calculator/computer technology in past posts. This time, I want you all to go to your 500’s (yes, these are cataloged with the sciences…) and weed your hearts out.
Mary: This reminds me of my high school math teacher who brought one of those super cool calculators to school to show us. Cost was around $100 back in the 70’s. Now I can get them free from my bank.
