Well, HP didn't, but there are many dozens of HP-35 emulators out there these
days (for PCs, PDAs, etc.). There's even one guy (Eric Smith) who wrote a CPU
emulator for the old HP calculators and built actual hardware (off-the-shelf
LCD and ARM CPU running the emulator) to recreate some of the old models. One
snag was getting a ROM dump... for the HP-35, they did it optically! --

10 microns! Now that's cool!


HP made the best calculator mankind ever saw, and may never see again.
My HP-11C ran a whopping 15 years on the first set of battery. $6 later
it had a new set and that's on its fourth year now. Modern equipment
goes like this: BIG LiIon Battery. Turn on ... hard disk grinding ... HD
grinding ... some more HD grinding. Battery is now down to 97%. Fire up
WP, write "Hello World" ... down to 95%. So yeah, my new processor here
is 65nm but what good does it do in a portable device if they can't
figure out a power efficient design anymore?
