9815 Tape Duplication - Katie - 06-17-2001 I'm trying to make a copy of the "Utility and Test" tape cartridge for the 9815A/S calculator. It contains a mix of regular (type 0) and HP special (type 3) programs. I can copy the type 0 programs just fine, but can't figure out how to copy the type 3 programs. The manual simply states that they are unlistable, but there must be some way around the copying problem. How does one make a backup of this cartridge? Thanks for any help, Katie
Re: 9815 Tape Duplication - Tony Duell - 06-17-2001 I believe the official way to duplicate 9815 (and 9825, etc) binary tapes is to use Re: 9815 Tape Duplication - Katie - 06-18-2001 Thanks Tony. But like you suggest, I don't have a 9877. I was hoping that there would be some obscure, undocumented instruction that one could enter to allow the ROM code to copy whatever's in memory to the tape.
