This module plugs into the mother board of the Model 80, and expands the standard 1Meg configuration to 2Megs. The module is currently in my system and has been running without any problems. I am selling the memory because of financial needs. I am asking $650.00. If interested please send me email. ------------------------------ From: "NJITX::HXN8477" Subject: 386 as a multiuser DOS machine Date: 8 May 89 11:44:00 EST Does anybody have information on running a 386 as a multiuser (not necessarily multitasking) DOS machine supporting at most 16 users? What I know is that this can be done if the 386 operates principally as a unix machine, with DOS applications being processes. How successful is this solution? The DOS programs that I am talking about are mainly Lotus 123, dBase III and MS Word. The users will use these programs seprately, i.e. every one will be working on his/her own file. As far as I know, these programs are 'well-behaved' in that they don't try to access the bios or write directly to the screen, ....etc. Will there be any problem, espcially if two users try simultaneously to invoke the same DOS program? If there are no problems, then (given a maximum of 16 user 1) What would be the lowest 386 speed needed? 2) What would be the minimum RAM needed? 3) What hardware would be needed in addition to a 'vanilla' 386, given that 3 users would access the system via modem? 4) Any recommendation for vendors? 5) Finally, is there a better solution than using UNIX as the multiuser vehicle? Any advice would be greatly appreciated.

I am thinking about purchasing a NEC 386sx PC. The price is right, especially in comparison to "real" 386 machines on sale in my area. Am not convinced that I need a 32-bit CPU as long as I can run UNIX (some form) and DOS. The 386sx seems a good choice . So has anyone else tried UNIX on a 386sx machine, especially NEC's?

Genetics, Univ. of Washington, Seattle Subject: 80386 versus 80387 Date: 12 May 89 04:39:39 GMT I have heard that there is a sporadic nasty interaction between 80386's and 80387 numeric co-processors, owing to a design flaw in the 80386, and that it is not cleared up yet. On a Zenith Z-386 I may be having this problem; when the 80387 is used there are sporadic unpredictable crashes or operating system paralysis (I happen to be using Unix, but if this is the problem that may be irrelevant). Question: are there 80287's fast enough to work with a 16 MHz 80386 (I think the answer is yes)? If so, would they suffer the same nasty interaction (i.e. can I cure this by replacing the 80386 by an 80387, or is that just jumping from the frying pan into the fire)? -------- Joe Felsenstein, Dept. of Genetics SK-50, Univ. of Washington, Seattle WA 98195 BITNET: FELSENST@UWALOCKE INTERNET: uw-evolution!joe@entropy.ms.washington.edu UUCP: ... uw-beaver!uw-entropy!uw-evolution!joe ------------------------------ From: Lost in mailing Subject: Beware of this vendor Date: Sun, 1989 May 7 19:00:53 EDT Warning, if you value your time and money, avoid any dealings with Micro 1 (557 Howard Street, San Francisco, CA). In mid December, 1988, they took my prepaid order for a '386 system, sent no written acknowledgement (but after repeated inquiries did finally fax an invoice 2 months later), and continually promised to ship "next week" until late April. At that time, faced with complaints from my lawyer, and no doubt from other customers, the owner, Rick McCabe, sold the company. The new owner immediately filed for bankruptcy. Micro 1 continues to claim that they will eventually make full refunds, but everything else they have told me was lies, so I have no reason to believe this is true. These people made a mockery of the FTC rules which are supposed to protect mail order customers. I publicly accuse Rick McCabe and Micro 1 of theft by mail fraud. Most likely these scum will change their business name and resume operations. If I hear of their new name, I will update this message accordingly.
