Isa cards to be active on amigas using a bridgeboard is like having 6 pci slots on the amiga in a tower and the mediator1200sx being the brdgeboard as so to speak.
I would not wait till i get an amiga 4000 just to get isa cards in there i would prefer to get an a1200 in a tower and get 6 pci slots instead.I think it's time to forget isa cards by now surely?
Also it will be better when www.elbox.com
come up with a newer mediator board with preferably 6 pci slots like the mediator1200 sx but with an agp slot so you can use better graphics cards instead of the pci version of the voodoo3 3000 etc....
I know elbox have the sharkppc+ accellerator card out by next year which will have an agp slot on it as well as pc memory slots etc......and that will require a pci slot on your mediator board.
So i think ISA cards are not so big in the amiga's today!
