HP-35 introduction
Hi, in this entry you wrote that the HP-35 could be ordered in 1968 or 1969 already. This is impossible. The development history of the HP-35 is quite well documented. While it may be possible that you got prototypes, the corresponding unified CORDIC algorithms were first implemented in 1971. It's easy to mix up exact years after all these decades, but if you still remember a year 8 or 9, my bet would be that you got your calculator in 1978 or 1979. --Matthiaspaul (talk) 03:17, 11 March 2019 (UTC)


 * Hi, in this case all of us (students at the Swiss Institute of Technology / Zürich) got prototypes or a pre-series. This was a collective order (at least 50 pieces) organised by one of us - we needed calculators for an examination either in 1968 or (more likely) in 1969. A later date is absolutely excluded.
