Since others would probably like to have this information, please respond to the net. Is there a directory of such facilities (including universities which have a supercomputer on site)? Thank you, Wayne Sonnen From chemistry-request@ccl.net Sat Jun 20 14:09:32 1992 Date: Sat, 20 Jun 1992 12:57 EST From: PATERLIN@msvax.mssm.EDU Subject: helix axis for non regular helices To: chemistry@ccl.net Status: RO Some time ago someone asked for routines that calculate the helix axis in the case of non regular/bended helices. However, I have lost his mail address. I'm also interested in founding out if such routines are available. I' will appreciate if someone can send me some informations and/or references about it. You can anwer to me directly (paterlin@msvax.mssm.edu) From chemistry-request@ccl.net Sat Jun 20 20:31:06 1992 From: Dongchul Lim Subject: Re: phone #s of supercomp centers To: chemistry@ccl.net (Computational Chemistry) Date: Sat, 20 Jun 92 18:24:56 EDT Status: RO WSONNEN@EAGLE.WESLEYAN.EDU writes: > > Dear netters, > > I would like to have a listing of all the supercomputer centers > in the USA; i would also like to have their phone numbers (1-800 numbers). > > Since others would probably like to have this information, please respond > to the net.

This very large file comes with both plain text and neat postscript format. I'll append a part of README file. -dongchul lim * README * You can FTP the resource-guide files from nnsc.nsf.net with a standard anonymous FTP connection: The Internet Resource Guide hierarchy is organized as follows. Material is divided up into chapter and section. Each chapter has its own directory, and each section has its own files, one for PostScript and one for plain text. So, to retrieve section 1.1 of chapter 1, you should FTP the files resource-guide/chapter.1/section1-1.ps (Postscript) resource-guide/chapter.1/section1-1.txt (Text) To simplify retrieval of entire chapters and chapter updates, or of the entire resource guide, you can FTP compressed tar files. The tar files for individual chapters include the recently updated sections; there is a file for PostScript versions and another file for text versions. resource-guide/chapter1-txt.tar.Z resource-guide/chapter1-ps.tar.Z The most recent changes to a chapter are in a file named chapter#-changes.tar.Z. These include the Postscript and text versions, only of the most recently updated sections. resource-guide/chapter1-changes.tar.Z Thank you for supporting the resource guide.

We want to be able to put our RISC-320H machine in one room and its 6091 color monitor in the next, the two connected by an R6-59U color co-axial cable. Can a person do that? We have two verdicts from IBM engineers. One claims that the monitor must stay very near the computer; the other claims the two can be separated by 200 feet or so. We made ourselves up some R6-59U coaxial cables and did some tests. If we keep the original, short cable between computer and keyboard, we can use 50 foot cables for both the video cable and the mouse cable. We find that when the keyboard is connected to the computer by a 50 foot cable, either the keyboard itself won't work, or the keyboard WILL work but the mouse won't work. When they ``don't work" they don't malfunction, they simply do nothing. The fact that the keyboard does work sometimes (albeit without the mouse working) leads us to think that it must be possible to separate computer and monitor; we think we're just overlooking something obvious. Can anyone offer us a suggestion? This is such a basic, useful question that I promise to publish the answer when I find it.
