To make a long story short im now in possession of a 486 PC from about 1992 if my research is correct. Its a Zeos machine that according to the previous owner was used for CAD in the early 90s? I wanna use it to play some DOS and early Windows 95 games but im not exactly sure what im able to upgrade on this system.

Right now it seems to have the following hardware installed

• A Zeos motherboard (This is also a Zeos system if that helps)
• An Intel i486 DX 50MHz
• An unknown amount of ram
• No L2 Cache
• A Diamond Speedstar 24 (Which from what ive been able to gather is a really good ISA 2D video card? So ill probably leave that as is seeing as I dont have PCI or VLB)

I wanna upgrade it to be closer to something around 1994-1995 in hopes that it might be able to play Duke Nukem 3D and possibly Quake? But im not sure what if anything are drop in replacements.

I was thinking about putting in

• A Cyrix 5x86 or Pentium Overdrive (Seems like a drop in replacement for this 486???)
• A Soundblaster Awe-32 or Soundblaster pro 2.0
• Some amount of L2 Cache
• and a Roland Mpu-401 compatible card to use with an MT-32 or something

Not sure how much of this is possible but thats why I figured id ask here since you guys probably have more knowledge about this than I do
