Hi,
I have just bought my first HP-35, and it works!
I am confused about which version I have - here are the details:
1) Buggy ROM - has all the well-known bugs including 2.02 ln e^x = 2.0
2) Has function names embossed on the keys - not on the case.
3) Front label says HEWLETT.PACKARD 35
4) Key 5 has the bump
5) No red dot on the power switch.
6) Rear label says "Made in the USA"
7) Serial number is 1143A 33435
Points 2 and 3 indicate a late version - but the other points indicate an early version (I think).
The calculator is in fairly good condition and has the battery pack - there is no obvious sign that is has been made from two calculators! ...
I thought HP fixed the ROM bugs before the version with embossed function keys! Any thoughts?!
