Which laptop?

Hello-I have a few questions that may be hard to answer.

I have an old mac plus that ran system 4.0 that had a bunch of old games such as artillery, dark castle, etc. About ten years ago I had a powermac 6300 (I don't recall what system it ran), that played some other games like prince of persia, Lucas arts games (sam & max, multiple star wars games), Marathon 1, etc. I still have all of the disks to all of those games (some are on cd, some are on 1.4 mb floppy, some on 800k floppy), but I don't have the computer anymore (the mac plus' monitor quit working.). I used to play those games all of the time growing up, and I wish I could just have a system that could play the games if I wanted to-they're quite nostalgic to me.

I found a program called basalisk II which emulates the old 6-7-8 systems. I tried playing some of them, and a few worked and most of them didn't. The ones that did work didn't play too well, and the sound was terrible. It's understandable when you're running OS X, emulating OS 7.5.3 or 8.1 playing games that were written for even earlier OS's. So I'm looking for a better option, which is why I am here. I see the older powerbooks, even the early G3's can run system 8.1 (my powermac G4 can't). My question is, which powerbook would be best suited to run all of my games? I need a cd drive and floppy drive. I would think the G3 powerbooks would work great, but I'm not sure if they are going to like the really old games. I don't know whether it is even possible to find one computer to run app's spanning 4 OS generations, but I seem to remember doing it a while ago so. I thought maybe some of you guys on here could give me some help. Thanks in advance!
