I dont think I have seen anyone mention OS 3.9 for the Amiga. It runs very well and if you add a Mediator board and put the 4000 into a tower case you get a very functional computer and its alot of fun working on the towerising project. The Mediator alows you to use some of the cheep PCI sound and graphic cards in your Amiga while still giving you Zorrow II & III slots for Amiga hardware.
