Tape Backup Software ?'s

by sinasohn＠ricochet.net

Does anyone know of a MS-DOS (pretend it's a 10yr+ old version) compatible backup program that can handle a SCSI DAT drive? I have *not* been able to find one. If you know of one, would you know where to find a copy now? Failing that, how about a windoze 3.11 program?

Does anyone know what power supply the Hanimex Pencil II uses?

by scott＠isd.canberra.edu.au

I have recently bought a second-hand Pencil II computer. This machine was made in the mid-eighties by Soundic Electronics. I have heard it was distributed my Hanimex, although there's no indication of this on the computer itself. Its microprocessor is an NEC Z80 clone, and it appears to have 16Kb RAM. The case is light grey and black, with dark grey alphanumeric keys and light grey cursor and function keys. Its BASIC comes on a cartridge which is inserted in a slot in the top right-hand corner of the unit. You can see a picture of it at http://www.insset.u-picardie.fr/museum/english/pages_museum/hanimex.htm (the only mention of the machine I've found on the Web). Unfortunately I do not have a power supply or any documentation for it. Could anyone tell me what the pinouts for its power supply are (the power socket is a four-pin DIN socket)? Thanks in advance.

9370 is a dog! Was: Re: Re[2]: Firsts

by Philip.Belben＠powertech.co.uk

I had a trip down memory lane yesterday - I cleared a path to the filing cabinet and got out my old IBM glossy leaflets. As well as things like "IBM 3090 - the Base for Growth into the Nineties" I found a couple of things on the 9370 series. I also found some stuff on PC graphics platforms and 3270PCs (of which more in my next). > At 12:30 03-02-98 -0500, William Donzelli <william(a)ans.net> wrote: >> >>Just because the sticker says 30 amps does not mean it will draw that >>much!

Ah. A 9375. Despite my joke and William's response, a 9375 model 60 has the highest power consumption of any in my catalogue, at 1.8kW - enough to heat a room, if not a house. (FWIW DASD = Direct Access Storage Device) If you are interested in operating systems, those listed for the model 60 were: VM/SP VSE/SP IX/370 (The AIX you were asking about) MVS (which won't run on the 9373 (model 20) or model 40.) There were also integrated packages carrying their own environment based on VM, which was then called VM/IS > Can't recall exactly, but total draw was about 11 to 12 amps or so when I Sounds about right. 11A at 230V is 2.5 kVA, which will do 1.8kW at 0.7 power factor (typical for a rectified mains power supply) with ease. Still dumped alotta heat! :-) We got cheap electricity in this town. $0.036 per KWH vs. about $0.08 or more per KWH outside of the area. Even $0.08 is less than we pay (typically $0.11). But we can get dual tariff systems which charge us the same peak rate and less than half that off-peak for heating etc. But I digress. Can't wait to work more with the system later this year if the wife has no additional remodeling in the new house for me to do :-( Have fun! Philip.

Strange how people in different (geographical) areas find different machines. In the [year + 2 vacations] I worked for IBM, I never saw a 9370 at all.

CGA Modes (Wuz: Win 3.0)

by Philip.Belben＠powertech.co.uk

The only piece of useful information about the 3270PC displays I could find yesterday was the resolution - 720 x 512 x 8 for the small graphics display, which I am now fairly convinced was a 5272. I don't know the scanning rates I'm afraid. Larry, you can get text on it with only one of the 3270PC display cards, which will indeed work in an XT. I'm curious that 720 x 512 (or 800 x 512) was so uncommon - it seems a logical (-ish) step up from 640 x 400. I was going to go on at length here about the PGC (PGA) and its display, since the marketing leaflet surprisingly gives a lot of info, right down to the connector pinout. But Tony got there first. Philip. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Assuming that all this is right (and I have no way of knowing as I'm using the 3270pc), I bet you could find VGA, EGA or CGA cards which could run a 3270 mode or a 5272 mode if told. It's a question of knowing what to ask and the software or firmware knowing. Someone had to be dumb enough to include it. Otherwise, what do you want for the 5272 $$? -Mike Lawrence Walker wrote: > > On 3 Feb 98 at 17:22, Philip.Belben(a)powertech.co.uk wrote: > > snip > > > > > I'm sure my 3270pc handles a "better" quality CGA.

You may need to revive the original machine or something similar in order to re-save the documents in ASCII. Conversion programs might be available, but that might cost $$$.

How much do 8" Floppies hold?

Shortly after that, the format died in favor of 5.25HD. Fair summary, except that I'd have said 'the format lives on in 5.25" HD' - IBM introduced the HD 5.25 inch diskettes to behave as much as possible like 8 inch ones, even though that meant different magnetic properties of the oxide from conventional 5.25". And IBM had enough clout that this displaced the existing 80 track formats right out of the market. IBM PCs that have HD drives have an 8 inch disk controller controlling them. So in summary, an 8 inch disk holds as much as a 5.25 inch one, although older formats held less... Now, does anyone know how much a 14 inch floppy held? (it was 14, wasn't it?) For that matter, who else has ever seen one? We had a drive at IBM which was bigger than the PC it plugged into. The disk (I only ever saw the one!) was in a white card envelope instead of the conventional black plastic one, and the slot where the head went in was along one of the diagonals, but otherwise I remember blank-all about it.

Ehehe... I've scanned my KK8-A board! Pictures online!

by DSEAGRAV＠toad.xkl.com

I mean, a paper is flat, and a board is (mostly) flat too, so why wouldn't I be able to scan it? Answer is, I can. It works fine. The only bug is the board is bigger than the scanner... I'll be retryin throughout the day, you can see the pictures at http://209.174.127.164/pdp8 Tell me what you think! Oh, and I wouldn't try this with anything with EPROMs on it... :) -------

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.

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.

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.
