If you want to use an HD biggenr than 4gb you need OS3.5 or 3.9...naturally,first you have to upgrade your A600...rom3.1,68020cpu and 6mb fast ram.
PS=it's easyest to buy a new A1200 or an second hand one...
To upgrade your A600 is more expensive and...i think that's also hard to expansions for this Amiga model.
