Please help a noob out here. I remember playing on old computer systems as a kid, but I was just recently thinking about taking a drive down to Salvation Army and seeing what old systems they've got for cheap. I've been having an itch to play old PC games from the DOS, Windows 3.0-Windows 98 eras. I currently run Windows XP and have heard all about the backwards compatibility issues with many games so figured that buying an old system may be the best route. I don't like using emulators and roms too much, personal ethical decision.
Some games I'm looking to run on it: Diablo 1 & 2, Doom 1 & 2, Baldur's Gate, Quake 1 & 2, Descent 1 & 2, Heretic, Hexen, Commander Keen, Alone In the Dark, 7th Guest, Icewind Dale, old Star Trek games, etc.
Questions before I look:
-Is Windows 98 Compatible with Windows 95 and Windows 3.0/3.1 software?
-In relation: Is Windows 95 compatible with Windows 3.0/3.1 software?
-Any system in particular good for what I'm looking to do?
-A 3.5 Floppy drive and CD-Rom drive should be all the drives I need for this era of stuff, right?
-Any recommendations on RAM amount and Video Card?
Thanks!
