A colleague of mine has purchased an IIT-2C87 for his Zenith SuperSport 286 laptop. He is absolutely delighted with it. He claims to have benchmarked this setup (12mHz, 0 wait states) at close to the performance of a '386 with Intel '387 chip, 16 mHz. I'm suspicious, and it certainly wasn't a formal benchmarking, but this guy knows his stuff, and he's very pleased with the IIT chip. ------------------------------ Date: Sun 24 Sep 89 20:37:07-PDT From: Randy Cole Subject: Alternative to Intel Math Chips I can't answer the question about the availability of the IIT 3C87, their alternative to the Intel 80387, but I do have a IIT 2C87, which is their alternative to the 80287. The 2C87 is indeed much faster than the 80287, and there are other reasons to prefer it (it's low power CMOS, versions are available up to 20 MHz, and it can replace either an 80287 or a 80C287). But beware of the following reasoning: If the IIT chip can add and multiply 5 times as fast as the Intel chip (which it can), then my (enter your favorite number crunching program here) is gonna run 5 times as fast. It ain't necessarily so. I have experienced an honest speedup of 20 or 30% with the 2C87 over the 80C287. Why? Simple. Let's say on the average that your favorite number crunching program spends half its time using the coprocessor to crunch numbers. Fine. Then let's say that it takes as much time to load the numbers (4 or 8 bytes each) into the coprocessor as it does to crunch them. Take a look at the compiled code sometime. Therefore that means only 25% of your program is spent actually crunching numbers. Therefore if the IIT chip is 5 times as fast the overall speedup is 20%. Bingo. Incidentally, the 2C87 has a new instruction that multiplies a 4 element vector by a 4x4 matrix. It's for 3D graphics, of course, and the speedup is very noticeable, partly because the 2C87 has registers you can leave the vector in between multiplies. The 3C87 is almost certain to have the same instruction but some legal hitch keeps them from saying explicitly that it does (that may have changed by now). I'm very happy with the 2C87. It will definitely speed up number- intensive programs. I'm not sure, but I think you'll find that IIT didn't explicitly state that an application would run 5 times faster -- they probably are smart enough to realize the media will jump to that conclusion.

There are two ways of accessing the archive: by ftp and by email. To access by ftp use the command ftp mims-iris.waterloo.edu or ftp 129.97.129.116 and using the standard ftp commands. Currently our ftp daemon is picky about mget patterns so if you want all the special fonts you should use mget ./spc*.sfp.Z instead of mget spc*.sfp.Z To access the archive by mail, send mail to one of the following addresses: font-server@mims-iris.waterloo.edu font-server@mims-iris.uwaterloo.ca uunet!watmath!mims-iris!font-server The font server limits the volume of fonts sent per day, and small requests get priority over larger ones. In the message body include a command for the server. Valid server commands include (but are not limited to): help send index send laserjet rom10.sfp.Z Please use ftp if you have access to it; mail is more demanding on everyone's system resources. All font files will be sent as uuencoded shar files. \tom haapanen "now, you didn't really expect tom@mims-iris.waterloo.edu my views to have anything to do watmims research group with my employer's, did you?" university of waterloo ------------------------------ Date: Mon, 25 Sep 89 18:54:12 EDT From: dmg@retina.mitre.org (David Gursky) Subject: MS-DOS Archiving software... I'm unfamiliar with the MS-DOS world, and I need some advice about archiving applications. One of MITRE's clients is looking for an application akin to Stuffit in the Macintosh world. Not only must the application be able to compress a file (via Huffman, Ziv-Lempel, etc.), but it must be able to convert a binary file to ASCII and vice-versa (i.e. the word 64 (hex) in the binary file would be written out as the character string "64" in the ASCII output file). In the ideal world, we would like a commercial application (with the current paranoia about the Datacrime virus, the Government is being warier than normal about shareware applications), but shareware, etc. would do if no other course is available. I am not a subscriber to Info-IBMPC, so I would appreciate if people were to respond to my directly (dmg@mwunix.mitre.org). I will gladly summarize any responses not copied to the newsletter and post them to Info-IBMPC. Thanks!

Has anyone out there had any trouble with Everex Evervision Color Monitors? A friend is running an Everex Evervision Monitor on an Everex Step 386 machine with a Paradise VGA card. She has gone through 3 new Evervision monitors in 6 months! The screen goes click, goes blank and the power indicator light goes off. It just dies. There doesn't seem to be an odor emitted from the monitor when it goes dead. The dealer she bought the system from in Vancouver insists that no one else has had any problems with their Evervision Monitors and says the system or the VGA card is toasting the monitors. The monitors have been hooked into the VGA card with a gender changer connector. Someone has suggested that the gender changer may be the cause. Several questions: Has anyone else had similar problems with Evervision or other monitors?? Has anyone else had problems with gender changer connectors?? Or ... are we alone out there?? Any hints or suggestions will be greatly appreciated.
