That makes a lot of sense, since Mach uses as much memory as it can as a disk cache, making things go faster once you use them.

CMU is planning a new release of Mach this fall which will be independent of the AT&T license requirements and will be more machine independent. I don't know what the NeXT people are using. It is such a nice machine. I wish I could go to school & buy a machine at the same time. I wish I had a BMW I could sell for a few bucks. Mike

There's no motherboard, unless you count the first CPU card as a motherboard. Everything plugs into the NuBus, not into the CPU card. >What is really on the CPU board (030, 882, and 1M memory?) Everything is on the one card. >How much memory is in the base configuration? 8Mb. -=- Zippy sez, --Bob Where's SANDY DUNCAN?

I'ver finally had it. Someone (Steve Jobs) FINALLY introduces what appears to to a superior product to the market, and all I've seen so far on the net is flames. There have been some well founded comments, like the problem of distributing software on $50 disks (although for some unknown reason no one has mentioned tape cartridges yet, although most of us have them on our Suns). The one comment, though, which really got my goat, was someone's complaints about the price tag. Well, let me tell you something buster: recently, I compared the price of a Sun 3/60 to a similarly equipped IBM PC AT with the same software (or as close as you can get in the MSDOS world). And guess what, the Sun was cheaper. And, is there anyone out there who wouldn't rather own a NeXT rather than a Sun? Isn't the NeXT more powerful and come with more software than a Sun? By simple logic then, the NeXT IS cheaper than an IBM PC AT and almost certainly less than the IBM System 2 stuff. But more importantly, who would REALLY want to own one of those IBM pieces of garbage anyway? COME ON FOLKS!!! Flaming is fun, but based on what I have been reading, the NeXT computer almost seems the the panacea for my home computer. As soon as a color system is announced, I plan to buy one. Lets see some more constructive discussion instead of random flames. gerry roston, robotic systems research group jet propulsion laboratory, 4800 oak grove drive, m/s 23 pasadena, california, 91109, (818) 354-9124 (818) 354-6508 roston@robotics.jpl.nasa.gov
