>>14539 Before Win95 came along, pretty much everyone had the choice to use GUI or not. DOS computers with 640 KB or less were very common, and capable enough to do most office tasks, like word processing, spreadsheets, and whatnot.
My aunt had an old Amstrad PC1512 that she used through most of the 90's to do all her stuff, including Internet. This particular model had 512 KB RAM, two 5.25-inch floppy drives, and a 2400 baud modem. Also it had a nice dot matrix printer that she used to print letters, and (postal) mailing lists, and other stuff. This was a perfectly adequate setup for all her tasks, because--get this--everything including the Internet at the time was mostly text-oriented!
In fact, if you really wanted to, you could have just as well used an 8-bit computer for all that stuff back then. You didn't even need graphics at all, and most of the early CP/M computers that could run WordStar didn't have any graphics. Like, if you wrote a byte to the video memory, you'd get a character on the screen. And IBM PCs themselves didn't necessary have a graphics card either.
