Are there any compatibility issues ?
Are there some games which would expect 512KB Chip RAM and then crash if they find 1MB Chip RAM ?
Both machines would have 8MB of fast RAM.
of the very few that exist you can probably find a patched or whdload version of the game that will run...
I don't recall ever needing to set my minimig 1.1's chip ram to 512k. 1MB on a few things.
