So let me get this straight. If I have "Dirty ROMs" and I have 20MB installed. Will it show as having 20MB in the About Finder menu? (but in fact only have 8MB usable until I use…

LCGuy is correct on that. IIfx ROM-SIMMs are 32-bit clean. The only issue you'll have is a bit longer of time to startup the SE/30. Sometimes it can vary depending on how much R…

There were "mainstream and popular games" for System 6 as well as System 7. You will be surprised at what still runs under System 6. For example, Deneba Canvas 3.5 runs wonderful…

Oh and is there any reason to go with System 7 over 6.0.8? I don't know how the compatibility is with games. I know some games need System 7 and I assume some won't work with any…

Bumping my old topic. I may pull out my SE/30 to replace my Classic now. I've noticed that some games play alright on the Classic, but they're slooow. For example, I was play…
