Hello Again... Either my first version of this post was lost, or no one knows the answers but I'll try again... Does anyone know if NeXT had addressed the problem of high speed modems being used with the serial ports? I read in a back issue of Tao that the NeXT has problems because it doesn't support hardware flow-control. Is this true with the new machines? What about SLIP? Is there a NeXT-supported or PD version? I currently plan to buy either a color station or a cube. I have concerns that 16-bit color with no graphics processor will be slow for things like animation, etc. I also think that 32-bit color (and it's price tag) is overkill for a home setup, beside that fact that I'd have to wait a year or two to get color that way due to it's price. Has anyone seen a color station in action? If I end up getting a cube, is there room to put a second drive inside it? That would make two hard disks and a floppy. Just a thought: wouldn't it be better to have an external floppy with the cube so that you could get a long cabel and put it beside the monitor on the desk while the cube was under the desk? You're more likely to want quicker access to a floppy drive than, say, an optical. Is it now impossible to buy a cube/40Mb hard drive/external floppy setup? For the first time, I just got to sit in front of an '030 cube for an hour and give it a test drive. It was great. I could live with that performance. It seemed to be quite similiar to my MacII, except for some program launches. I can't imagine what it will be like on an '040 and with all the improvements to the OS, I'm dying by inches to get my own... Thanks for any info yo can give... tjb ____________________________________________________________________________ | Thomas J.

Yes if you buy one of the new machines or upgrade a current 68030. > What about SLIP? Is there a NeXT-supported or PD >version? Yeah, what about it? Over a year ago Avadis Tevanian, Jr. posted that he had a working loadable SLIP. To my knowledge it has never been released to customers, and we never got a straight answer on whatever became of it. > Has anyone seen a color station in action? Yes. >If I end up getting a cube, is there room to put a second drive inside it? >That would make two hard disks and a floppy. Yes, if one of the hard disks is a half-height 340MB or (yuck) 105MB. If you want two full-height internal drives, you can't have an internal floppy. >Just a thought: wouldn't it be better >to have an external floppy with the cube so that you could get a long cabel and >put it beside the monitor on the desk while the cube was under the desk? I don't know about "better." It's certainly going to be more expensive. -=EPS=-

I am thinking of selling my Mac II and purchasing a NeXT. Could someone post the (Dhrystone 2.1, SPECmark, Whetstones) for a 68040 NeXTstation? Thanks, Don W.

From: uunet.uu.net!cbmvax!cgh!paul (Paul Homchick) Paul Homchick (cgh!paul@dsi.com) advises: >1 Dhrystone MIPS is how many dhrystone/s the VAX 11/750 does. It does >something like 1574. So the NeXT is 15*1574, which is around 23000. Based on InfoWorld (Oct. 29, 1990): For comparison, a 25-MHz 486 comes in at 20 Dhrystone MIPS and an IBM RS/6000 Model 320 is 27 Dhrystone MIPS. It's easy to slant the results, though, by handcoding, running entirely in cache with no misses or main memory accesses, or even writing compilers to produce the fastest sequence of operations for the benchmark programs. Consequently Spec, Inc., was set up to establish a vendor-independent benchmark, the Specmark. Here are some Specmarks: Sun SparcStation SLC 7.6 Compaq Deskpro 486/25 8.7 Sun SparcStation 1+ 10.0 Sun SparcStation IPC 10.0 Solbourne S4000 12.0 IBM RS/6000 Model 320 22.3 IBM RS/6000 Model 530 28.9 Does anyone have the Specmark rating for the 68030 and 68040 NeXT's? ------------------------------------------------------------------------------- Walter C.
