Stuff, while we're at it...

Thanks. I'm in Ohio, 44857 As I understand it, you have a complete system, with a (fuzzy?) monitor? Is there a HDD, or is that the bernoulli? Is there software?

EPROM programming voltages

by yakowenk＠cs.unc.edu

Can anyone point me to an on-line reference showing the necessary voltages for programming various EPROMs? I'm especially interested in the oldies-but-goodies: 2708, 2716, 2732, and 2764's. In particular, it seems some of them want 25v while others want only 21v, and I suspect that even the same chip number from different manufacturers may want different voltages. Thanks, Bill.

Video connectors (was: CGA Modes (Wuz: Win 3.0))

This is a tri-density upright unit with formatted Pertec interface. It worked the last time I used it, but, as I look at it now, it appears that the backup battery on the CPU board has failed. It would likely be necessary to run through the calibration procedure after replacing the battery. (I recall doing the calibration before, so it must be in the manual. These drives have an RS232 port to control the diagnostics.) I also have an extra drive (with mechanical problems) for spare parts; they should probably go together.

K&E made a bamboo one, too. (At least mine looks like bamboo -- it certainly isn't mahogany). I was told that bamboo has a low coefficient of linear expansion, which is why they used it. manney

<example, certainly is.

Par of the resoning was that it should have a connector that is not like any other. if it were a standard db9 or db15 you'd have people plugging into the serial port screaming it don't work. It's bad enough that you have people that will force things no matter what. Allison

No, the first Windows NT was V3.1 which matched the current shipping version of Windows at that time. IMHO it was not even close to any reasonable version of Unix but was/is much easier to configure.

<NT prior to 3.x was called MS LAN Manager, and didn't compare particularl <well to anything. NT prior to NT wasn't. NT was a divergent design that is non dos filesystem. LANMAN is the networking component of WFW3.11. The divergence from OS/2 and windows3.x was also influenced by MS getting Cutler an OS heavy that created DEC RSX-11 and early VMS incantations. the idea of NT was clean sheet 32bit OS with multitasking, multiprocessing and inherant networking all of which were glueons for windows. OS/2 was a different path from NT with a different base designer. In reality NT is not a stand alone OS as it requires windows as the user interface wher OS/2 it was a add on. Also the roots for OS/2 go back further and it was the DOS replacement with all the things that DOS still does not have. Allison

First off, LAN Manager was a network product, not an operating system. LanMan Server ran on top of OS/2 1.x, and LanMan clients were available for MS-DOS and OS/2. LAN Manager 1.x was an OEM product and was not sold by Microsoft. It was available as 3Com 3+Open, IBM LAN Server, etc. LAN Manager 1.x was a first generation product, but LAN Manager 2.x performed well and was the first network product to capture significant market share away from NetWare, where many others had previously failed. LAN Manager 2.x was also the first network server sold directly by Microsoft. Kai

Microsoft OSes

by kaikal＠MICROSOFT.com

First of all, did MS Xenix run on PC hardware? Yes, 286 and above as I recall. Introduced August 1984. Secondly, was there ever a Windows NT 1.0 and 2.0? In a sense, this was OS/2. OS/2 1.x was a cooperative venture between Microsoft and IBM, with the majority of the OS/2 core designed by MS architect Gordon Letwin (ref: the 80s book _Inside OS/2_ by Letwin, MS Press). The first version of Windows NT, 3.1, arose from a difference of opinion between Microsoft and IBM over the future of advanced operating systems; a difference of opinion created by the huge unanticipated success of Windows 3.0. After the Win3.0 release, IBM and Microsoft development paths diverged, with IBM focusing on OS/2 2.x, and Microsoft on Windows 3.x. Both continued work on their 3.0 releases of advanced operating systems, which became OS/2 Warp and Windows NT respectively.
