Okay, thanks everyone, that explains a bit..
By the way, regarding 020
This only upgrades the memory right? Been looking at accelerators on amigakit, and correct me if I am mistaking but 020 card runs at 16mhz it says, and this is the same speed as 1200 runs on?
And if I would upgrade, where can I get a hold of wb 3.9 to try it out? Can it/does it have to be bought? Or can it leagly be downloaded today?
