Once again my comments to the modern HP-calculators...
I guess that you already noticed that I'm collecting the calculators of a Dallas company - known as the inventor of the single-chip calculator. If you are interested in my collection covering more than 700 TI calculators just convert my email address with the www. header to a web-address.
TI collectors and HP collectors are somewhat similar - not too happy with the modern products and still remembering the fights between HP-35 vs. SR-50, HP-65 vs. SR-52, HP-67 vs. TI-59 and finally HP-41 vs TI-88 (sh**, here we lost..).
About two years ago I purchased the whole set of the modern Two-Liners introduced by TI to compete with the Sharp and Casio line of that product category. We know the TI-30X II, TI-34 II, TI-36X II and TI-40 II. When Hewlett Packard introduced with the HP 30S a similar product (sorry - I ignored the HP 6S, in my opinion not the best of its kind) I immediately felt in love with it!
Why ?
It corrects all flaws known from TI's product line:
* Battery access without removing the housing.
* Common LR-44 batteries instead expensive CR-3025
* Brighter display
* Improved accuracy
Everything else is identical to the TI Two-Liners.
Yesterday I compared both a TI-30X II and the HP 30S carefully and revealed a big surprise: The internal construction of both calculators carries the same handwriting. One is called SR16 and the other SR18.
The step from the TI-30X II to the HP-30S demonstrates with the reworked PCB architecture the usual process of cost reduction.
