Dave should also be careful when stating that *most* NeXTs can't add another processor too. True, that the new ones don't have an expansion bus, but a few of the older 'cubes' were sold. One of the (5 I believe) NuBUS slots in the cube is the processor.. so in these boxes, you could just add another. I'm not a next advocate, I'm just stating a fact. > >>jonas > > >-- >Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" ^^^^^^^^^^^^^^^^^^^^^^^^^ Ahh!! Now we got him!! He must be perty tired by now, or does this new rumored 'Amiga 3000 Crew' have sleeping disorders? Do they have more colors? More slots? I heard they come with 4 040's running in parallel under AmigaDOS, and a 50 foot true color monitor. :-) -- Michael M Morrison /| |\ mmm@reaper.chi.il.us | | Cash, for Cache.. | | reaper!mmm@miroc.chi.il.us \| Hmm.. sounds fair. |/
