The SLC is $5.5k including -8M of RAM -a 17" screen of resolution 1200x1000 or so -FP hardware -12.5 mips. With a 500M disk, the cost comes to $7.5k or so (does someone have exact disk prices?). The best available 486 does something like 8 mips. 8 meg of RAM is $800 or so. How much is a 17" mono display with 1200x1000 or so? And a .5G disk? Basically, how do the contenders play off?

Well, the price of an SLC is $4995, and what a deal that is! But, Unix (SunOs) and Open Windows costs $350 (they are now bundling the two) and the complete set of manuals is $600 for Unix and Open Windows. The disk business is strange. They just cancelled their 327MB Disk/150MB Tape package and are now selling a 669MB Disk/150MB Tape package for $6500! So, it looks like your storage costs are going to be the major investment. Apparently you can hook up around 20 SLC's to a single disk (or SLC server) and not see significant performance degredation depending on what you do - this of course was from a Sun salesman! Greg.

On a whim, I looked up the price of a 600+ MB SCSI DISK in Computer Shopper and found several for about $2300. Does anyone know what disk SUN uses? Is there a compatible disk? What about replacements for the 104MB SCSI drive, and the 150 MB Tape unit?

I saw a system set up like this (DACNet at the Design Automation Conference), and it was trash! The reason: when you are running Open Windows, an 8M SLC will thrash memory. Put twenty of those running swap off the same disk and you have a disaster. If you run any windowing system at all, anything with a local disk for swap will outperform a diskless node with the same amount of real memory, unless that amount happens to be large enough to avoid swapping altogether. I have found that I tend to use up whatever real memory is there by enhancing my basic layout, so I'll never have enough real memory to do that :-) An aside: Sun was there in force at DAC, knew about the mess called DACNet, yet they made no attempts to remedy the problem. I thought that such negligence shows a remarkable arrogance, not unlike another 3-letter company we all love to hate.
