How They Do That Manual Hi Res Scan (HP 9825 BPC 16-bit processor)

Thanks Mark, very cool. For those interested, guess most of the story behind the BPC is on Steve's site (http://hp9825.com/html/hybrid_microprocessor.html). F.Ulivi wrote the MAME emulation for it. I

I believe that the BPC was also used in the original HP64000 in-circuit emulator family. Arnie

Heads up that I posted a new high resolution scan of the How They Do That manual for the BPC hybrid processor. Too big to fit here, so I uploaded it on the internet archive: https://archive.org/detail

I have unearthed a 98034A HPIB adaptor for the 9825 calculator. I don’t have anything else related to this unit - although there appears to be plenty on the web. If anyone would like to make me an off

I could do some if needed when I’m back from travel in 2 weeks, but I see Craig replied already, so I assume you are covered by the Master himself. Let me know if you still need some additional. Marc

Hi, I'm working on improving the visual appearance of my MAME-based emulation of HP9825. This is the current status of the HP9825T system: All keys (including RESET & SHIFT LOCK) are emulated. I also

Recovering binaries from 9825 tapes
#HP9825
As far is I can see at the moment, that won't be a problem. Read/write amplifiers for the 9825 are the same as for the 9845. The 9845 used the same tape drives as the 9825 only the last versions have

Recovering binaries from 9825 tapes
#HP9825
Nice work! I wonder whether the magnetization level of a real 9825 tape is compatible so that it can be reliably read on a standard 9845 tape drive module. It might be necessary to check with a scope

Recovering binaries from 9825 tapes
#HP9825
So, it took a while but I think I have something to try to dump 9825 tapes on a 9845 machine. All of this was developed & tested on emulated systems so I'd like to know if someone is willing to try it
