Nice. Except that Mode X was not usually called 13h. The former would be 320x240 and the latter 320x200. Technically X would be a variant of the 13h, though.

- gneissguise 1y agoThank you both for the corrections, I was a teen in the 90s so I could have had it wrong or misremembered. I just looked up the 13h interrupt and you are absolutely right!
- kookamamie 1y agoAn awesome contribution nevertheless!
