Not certain of whether you’re thinking specifically of plain ASCII art or also ANSI art (which was specifically around that time and made use of PC drawing characters and ANSI escape sequences), but there’s a software package called ansilove that will render ANSI art, as well as some related text art formats, into an image for viewing.
https://16colo.rs/ is a gallery of ANSI art. A lot of the thumbnails are in grayscale, but tap on them and they’ll open up and have a lot of colorful artwork.

It’s packaged in Debian Trixie.
