I have had a chance to "play" with the NeXTstations on campus once or twice, and I'm impressed by them, but I don't know much about the specs on the actual system. Could anyone out there give me some idea of the speed (i.e., the performance of the 25mhz 68040 vs., say, a Mac ][ci or ][fx) the video (I'd really like to know the resolution of the color system...), and any information on expandability. I had heard that the NeXTstations were designed to not be directly expanded like the "Cube". Any info is greatly appreciated... B
