1981 CAD Monster – HP Series 200 9836C



The HP 9836 computer is incredible, expensive, uncommon, and unknown. I am so excited to have this one and thrilled to get it up and running!

  1. I remember as a kid looking at Tandy computers in the early 1980s and they started at $2000 in Australia – it may was as well have been $20,000 for all the average teenager could afford. Thank God for Commodore and Jack Tramiel.

  2. regarding the disk interleave problem:
    You could reorder the sectors so that one disk image could be transferred to a different disk with different interleave. But of course you'd need full knowledge of the format and file system to transcribe one disk image into the other.
    It's really great you found the GPIB hp drive emulator instead !

  3. Wow. Another example of unique, "general-purpose" custom machines from back-in-the-day.
    So much design and effort went into this system…is it simply the cost that prevented this from being more widespread & common use?

  4. Yay! I feel kinda smart… Not knowing anything about the HP ecosystem, my immediate thought when you were talking about the incompatibility of the disk images was "Well, can't you emulate the drive or otherwise stream the data to the machine from something that can read the images? 🤔"

    That's kind of sad though… Obscenely expensive vintage CAD workstation, and no one's preserved any of the CAD software for it. 😢

  5. I worked in Aerospace in the late 70s, early 80s and the HP Controllers were used for automated testing of control systems using the HPIB. I worked with the predecessor, the HP 9835 and later the 9826. I don't remember using a 9836, but I know I've seen one. I remember seeing one in an "old parts" storage area and I would love to get my hands on it.

  6. Looks like they pulled the engineers that did their test equipment to design and build it. Multiple backplanes, beefy supply, tons of expansion and everything and built like a tank.

  7. Any updates on the g4 imac with processor swap and the a1283 mac mini i think it was when you made it a socket CPU? I just picked up a 1283 Mac mini myself and I want to put the best operating system I can any recommendations for pre-and post processor swap? Thanks man I love your show.!!!!

  8. You are so beautiful, God !
    Did you really have to ruin my day?
    Look at the videos of the Thais,
    they know how to present something without being seen

  9. Oh my, what a blast from the past. I have one of those in climate controlled storage, just can't remember the state. I know I have everything for it. Terms of system disks and such. It was a wonderful machine. I created guitar, violin, etc. Components on it. I don't know as I recall I did everything in basic but I can't recall. Hopefully my kids didn't get into that unit and sell everything in there.

  10. Still rocking that MX518? I left mine at a job more than 10 years ago. It was the first "gaming" mouse I ever bought. …but I suppose all of my mice have been gaming mice to some degree.

  11. HP have lost me as a previously dedicated customer. My most recent purchase of a HP laser-jet printer has been nothing but trouble. It doesn't matter how closely I follow their instructions, Wi-Fi printing works once and once only before I have to delete the drivers and start again. This has put me off the brand and I'll be trying one of their competitors next time.
