It's easy to forget how different the home computing world was in the 80's and 90's. Personal computers weren't as standardized yet leading to households having a variety of options by Atari, Commodore, and other companies. It wasn't uncommon for game console makers to offer their machine as a home computer on it's own.
At the time, it wasn't a terrible idea. Most home computing revolved around word processing, spreadsheets, random software for various tasks, and of course games. The internet was a lot more limited than it is now and even what it was by the end of the 90's. The Mega Modem was a reasonable solution for online needs at the time, even if it was a bit slow for some things. A lot of time has passed since then and they way we compute is way different now. But man, there's a certain charm to those old micro computers that just can't be replicated.
