In this show and tell video, I explore my upgraded IBM 5150, the first DOS PC. I show how to get EGA graphics on a CGA monitor, how to capture the video output in the best possible quality (including PC speaker audio), how I connect this PC to my home network to transfer files, and also a DIY overclocking solution called the PC-SPRINT.

This video was created as part of DOScember, a collaboration between retro tech YouTubers celebrating all things MS-DOS!
