Repairing a $25K HP Workstation from 1981 to Run Pac-Man
- mozman 3y agoI thought for a moment this was from Curious Marc[0], who has an addiction to vintage HP gear although mainly from the 60s and 70s. I have no affiliation but if you like vintage computing he has quite an amazing video collection, including restoring and using gear from the Apollo mission.

- gbraad 3y agoThis is most likely Tech Tangent. In the end hed details how the disk images messaged by the hp museum are hard to repro. Glad he deals with this, otherwise they could have been preserved but still lost.
- SOTGO 3y agoIt's not Tech Tangent I think. In the article he writes "some of the disk images [Tech Tangents] found at the HP Computer Museum" which implies to me that they're different people working on similar machines. Also Tech Tangent's name is Shelby, and this author is going by Robin Kearey, who seams to be a real person.
- gbraad 3y agothe article is about the Tech Tangent video, that is what I guessed and it is. the article writes about the dodgy video cable... which is shown in the first few minutes. so whoever wrote it, made a summary. It plays pacman very shitty BTW, as the TSR control bar will stay on screen.

- anonymousiam 3y agoHP used an RPG (rotary pulse generator) for the wheel. I believe they were the ones who invented it. It appeared it lots of their test equipment too. https://picclick.com/Keysight-Agilent-HP-Avago-RPG-Rotary-Pulse-Gen-280725903683.html https://picclick.com/Keysight-Agilent-HP-Avago-RPG-Rotary-Pu...
- RicoElectrico 3y agoIs this a quadrature encoder or something more fancy?
- anonymousiam 3y agoI updated my comment above with a link. Just an ordinary quadrature encoder, but revolutionary back in the day.
- jacquesm 3y agoDefinitely not invented by HP though. https://www.usdigital.com/blog/who-made-the-first-optical-encoder/ https://www.usdigital.com/blog/who-made-the-first-optical-en...
- anonymousiam 3y agoOkay perhaps not, but in my experience, HP was the first company to use them as a human interface device (HID).
- jacquesm 3y agoLong before then I saw them on CNC gear that had nothing to do with HP.
