So, I've been having this AST Advantage! 7302 sitting around for about half a year or so seeing very little usage.

It's all original/stock as delivered in 1995 or so. 120 mhz cpu, 16 mb edo ram, 1.2 gb Seagate hdd along with a 3.5" 1.44mb drive and an 8x cd-rom from Hitachi. It's running its original Windows 95 installation.
I'm actually more of a late 80s / early 90s kid and was wondering if running DOS 6.22 (or some other flavor) would be a good idea? I'm mainly looking to play old SSI, Sierra and Lucasarts games and don't really have much use for what Windows 95/98 offers. Unless there are convincing reasons to use that?

As far as I can tell from browsing the Internet and checking the hardware through Windows 95 it seems to be equipped with and S3 Trio graphics cards and a Yamaha soundcard (OL3?).
I have an old working 5.25" TEAC drive that I could fit in the empty 5.25" bay in the front.

How would you go about utilizing this computer?
