Windows 98 is a memorable system to a lot of people. I grew up right in that era, my elementary school was set up wall-to-wall with Gateways in our computer lab, hours wasted on Kid Pix and the occasional flash games (the classic era of Macromedia Flash).
I've set up a 98 machine with an IBM Thinkpad T23, based somewhat on a laptop given to me by my older brother once he got a Dell desktop. Said laptop would be mercilessly smashed against a wood chest because I could never remember the BIOS password (retrospect: it was "advanced"). That was the first, and last high-cost device I would break intentionally. IBMs are tough, but they can't withstand it all.
I'm mostly in this stage to explore old games I used to play on Windows XP, but also to see how far I can stretch the system. I am shocked at how much I can do on a PIII and only 512mb RAM. If I wasn't so deep into Steam or Youtube, I could probably survive just using this laptop.
I very much wanna see what "current" things I can pull off with this machine. Maybe try a super-old copy of Adobe Premiere, see how far that takes me.
