Frequencies of the HP-41 TONEs - STOX - 01-11-2023 10:45 PM

Could someone point me to the frequencies of TONE 0-9 and the length of the tones in ms?

I do not have a complete answer for you but here is a partial one: (48G,50g) HP 41C style BEEP

The source is the Wickes book on synthetic programming which I do not have, so if you can get your hands on that book you can probably have a complete answer.

Does Page 24 from the "HP-41 Synthetic Quick Reference Guide" help out?

Google for "hp41-synthetic-qrg.pdf".
