I only collect the "desktop" machines, e.g., 9100A, 9100B, 9800-series,
46, 97, etc.
I love the old HP calculators. The 9100's are one of the most elegant
electronic calculators ever built in my opinion. Doing all that with
just transistors, and in the compact size of the machine is simply
amazing.
