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

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'
