Throw some 3.1 ROMs in that baby and check out this:

http://www.amiga600.de/index.htmThe indivision video upgrade looks great in an A600 ECS setup. I even see 68030 based A600 accelarators for reasonable prices.
I am thinking of cranking up one of my old Amiga's just to try this BetterWB package. While I run a modernized machine, part of me wants to get an older machine running that is more of a legacy setup. An earlier post here referenced the Build a Better Workbench series. I once went through much of what was presented in that series in the updating of one of my machines. That was before the day before preconfigured OS packages....
Have fun with your new machine!
