Tony,

Today I took the time to read the main page of your website and I am very impressed with all the details you provided on HP calculators. I'm still in awe of the incredible technology packed into the early HP's. When the HP-35 came out, I was using old rotary Monroe calculators at work. Trying to do multiplication or division with those old warhorses was quite interesting and the machine put on quite a show. But at that time an HP-35 would have cost 4 months rent or more, so I waited a few years and bought a $30.00 Qualitron, with an 8 digit display and reciprocal, square root, square and X<>Y key and when I started using it, I thought I had a super computer. I can only imagine what I would have thought with an HP. Now I have several HP's from their first decade. So I can well feel the excitement you must have felt when you got your HP-45 ! I really appreciate all the detail you have given in your web page. Helps us to understand what is going on inside.
