You have done a great job of restoration there Chris. It just occured to me that thankfully I started 'collecting' HP calculators before you, otherwise you would not have them now.

I spent many hours using all three before computers were practical. It was easier and far more accurate to do calculations with a HP than sit down and write the machine code as memory was very limited in those days. Ever tried to use a DEC PDP8 with 2k of memory?

It gives me a lot of satisfaction that they are in better condition and in safer hands now. The fact that in your capable hands they are working as well is a real bonus!

My ex wives used to tell me off for never throwing anything out. Seems like they were the only ones that were.
