This machine is used mainly for playing old graphics adventure games (Like Sierra On-line classics). And some -1990 racing/simulation games, like Indianapolis 500.
All games up to EGA/VGA 16 colors graphics works fine of course. Some early VGA 256 colors games are still playables

PD: Sorry, no editing, and maybe low/high volume on videos. I do this on my free time. It's my de-stressing hobby.

Very nice build!

I have my turbo XT configured with EGA graphics because all of the 16-colour games look really fantastic when displayed on a 200-line CGA monitor (mine is the Philips CM8833-II). Secret of Monkey Island and LOOM are at their peak IMHO when you can see each individual scanline! The artwork looks less pixellated/chunky and more "vivid" -- I suspect it's a combination of a larger dot pitch (compared to a VGA monitor) blurring adjacent pixels together a little plus the scanlines giving some texture to the regions of solid colour.

EGA monitors are very hard to find but nearly all EGA games actually just use the 320x200 mode which is 100% compatible with any standard CGA/TTL monitor.
