I would replace it, but it actually seems quite fast! It sure surprised me, but it opens fast, and I'm never waiting on the disk. I think the only limitation is the RAM at the moment, but as soon as I add that, I'm sure there will be something else slowing me down...

Got my favourites on there at the moment, After Dark with Lunatic Fringe, Maelstrom, Sim City 2000, and of course, F/A-18 Hornet 2.0, all on System 7. I am 12 all over again!
