Harald, I do not accept politics of modern business. Firms SHARP, CASIO, JVC and others sold in the USSR their products together with all charts. I personally bought and I know. Now replacement of resistor for repair of HP is comparable with a moon flight. I do not understand this secrecy.
Purchased 3 brandname things of SHARP ZQ - 201b in new condition for $20 for them all. But to give monthly earnings for the arithmometer of HP - 25 (salary for a month in the Ukraine is $170) - I do not see any sense. For example, I bought in 2014 AFX - 2.0 (made in China with fake serial number), but this was a complete dung. I have real AFX - 2.0 (made in ..., and I know it).
95...99% of engineers, that checked my two HP - 50 and one HP - 48gii, declared that 48gii is of real HP-quality, but not HP - 50g. Very strange quality for the modern brand?! It is disgrace for HP
