🎄💾🗓️ Day 5: Retrocomputing Advent Calendar - Compaq DeskPro 1 🎄💾🗓️

The Compaq Deskpro Model 1, introduced in 1984, featured an 8 MHz Intel 8086 CPU, which had better performance than the IBM PC's 4.77 MHz 8088 processor. It combined Color Graphics Adapter (CGA) graphics with high-resolution Monochrome Display Adapter (MDA) text, delivering enhanced text display. This improved speed and better text clarity over IBM PCs equipped with standard graphics. The Deskpro's architecture allowed for various disk configurations and was an influence for many personal computers.

And here's a somewhat "first computer" story from Adafruit team member Anne!

"In my first year of EE (junior) we were limited to larger computers. My senior year we could check out Compaq Portables (really luggables) which allowed us to run C compilers and compile cross assemblers onto a machine for ease of use.

When I graduated, I needed a computer and went to a PC store. They contrasted the IBM PC/XT 8088 with the newly released Compaq DeskPro 1. With an 8086 processor running at 7.16 MHz, it was faster. It came with monochrome graphics (green or yellow) with both CGA and text mode video. I bought the dual 5.25" floppy version to start, to have enough money for an IBM ProPrinter for output.

The machine was great and I spent many hours on programming, databases, word processing and more. It was upgraded eventually to a 30MB RLL hard disk and an added 720k 3.5" floppy."

It got through the '286 era and was supplanted by a '386 machine. I still have the DeskPro and I intend to resurrect it in the not too distant future.
