Exploring the Compaq's first desktop computer from 1984: The Compaq Deskpro

Video Description

Part 1. This is Compaq's first desktop computer released in June 1984, two years after their highly successful and 100% IBM PC compatible Compaq Portable. It borrowed the trick dual mode monitor and graphics card from the Portable and offer a lot more expandability. In this video, we'll start the process of diagnosing and testing the computer. Let's install a XT-IDE card in the machine and see what it can do. I also figure out how to control the CPU speed and key-click function from DOS. Toggle CPU speed: CTRL-ALT-\ (power LED changes color) Control key click: CTRL-ALT-+ and CTRL-ALT-MINUS (use the numeric keypad) Change between high and low red video mode: CTRL-ALT-'LESS-THAN' and CTRL-ALT-'GREATER-THAN' Part 2: https://www.youtube.com/watch?v=wdFm91gAs_Q&t Part 3: https://www.youtube.com/watch?v=ILFVoZksjNc Part 4: https://www.youtube.com/watch?v=WrLRKqDvUxE Apple IIc repair video: https://youtu.be/N8YVX75Qr-0 Links: Commodore Computer Club https://www.commodorecomputerclub.com/ Free VI For DOS: https://vetusware.com/download/Free%20VI%20Text%20Editor%201.9/?id=16067 Compaq Speed Control Scripts and tools: https://vetusware.com/download/Compaq%20Deskpro%20CPU%20Speed%20Utilities/?id=16112 CGA Compatibility Tester: https://github.com/MobyGamer/CGACompatibilityTester/releases Speed Test v0.99: https://vetusware.com/download/Landmark%20Speed%20Test%20v0.99%200.99 Checkit v3: https://winworldpc.com/product/checkit/30 IMD: http://www.classiccmp.org/dunfield/img/index.htm Free VI For DOS: https://vetusware.com/download/Free%20VI%20Text%20Editor%201.9/?id=16067
