I recently obtained a neat 486 system, the NEC Powermate 433D. The previous owner however must have done some upgrades in the past. When testing it out, I found Windows 98. Literally, there was a Windows 98 install CD in the disc drive. Besides that, the RAM and CPU I believe were upped. It currently has 16 megs of RAM and a DX2 @ 66 mhz. There is also a "fake AWE64" CT4520 SB16 card installed but everything else is onboard.

I'm not too sure if I want to switch out the processor or bump up the RAM but I was hoping to see if anyone has recommendations regarding sound and video. I'm aiming to run DOS and maybe Win 3.1 as well for any games that require it. I don't have a ton of spare parts to choose from but thanks to liqmat and past lucky finds I have a few options available without resorting to eBay.

Any thoughts?
