Stumbled upon this today, interesting info from someone who was an indirect contributor to the HP35 revolution.

Apologies in advance if it’s already made the rounds here.

Thanks! That was a very interesting article.

I liked the bit about the Mostek guys upgrading their HP-35's by swapping in HP-45 ROMs. That would be quite an eBay find!

Hello,

Super article! Thanks for sharing!
