9825, 9845 tapes and manuals
In looking through some old HP parts in the outer reaches of my calculator collection, I've come across a few items that may be of interest to others. Some are tapes and likely unreadable but I don't know if they're interesting enough for someone to try to recover.
HP/DC100 cartridges 'System tape cartridge' 09885-90035 - don't know what system no box 9845B Introductory Training Cartridge 09845-10124 no box 9825A System Test Cartridge 09825-90036 9825A and peripherals Manuals HP 9825A CalculatorError Messages 09825-90015 (a tiny quick ref guide) HP 9825A Calculator Quick Reference Guide 09825-90011 (2 copies) HP 9825A Desktop Computer System Test Booklet 09825-90037 I don't plan on keeping these if there's interest. If they're of no merit I might recycle the cartridges by trying to replace the tape on them. Would that be a crime ? I have a 9815 that could use them but don't see tape as a long term answer. |

RE: 9825, 9845 tapes and manuals
I will definitely preserve it, then.
However, is it so rare nobody's put a copy in an archive, or is it just interesting as original media ? Has anyone got sufficient low level experience of the 9825A tape drives to perhaps recover it even if it doesn't easily read ? Or if it's hard to copy, as Katie has described of some other maintenance utility ? And probably need to rebuild the cartridge first to avoid stripping all the oxide off the tape. |

Many people have been looking for one for decades. There are some people with the ability to extract the data safely if the tape hasn't been torn up by a sticking tension band.
