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?

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.

I was reading through this quarter's issue of the International
Calculator Collector. (The cover story is about the 30th anniversary
of the world's first "pocket" calculator- TI's "Cal-Tech" prototype)
They print an excerpt from Electronics magazine dated July 3,1972
that said that TI was test marketing their first calculator - The Datamath
in Dallas and Houston, selling for 149.99.
Another excerpt from a TI press release dated September 21,1972
states "A line of three new calculators introduced today marks the
formal entry of Texas Instruments into the electronic calculator market.
The three new calculators are the TI-2500 portable calculator and the
TI-3000 and TI-3500 desk models."
According to TI's calculator history page (Check out
http://www.ti.com/calc/docs/calchist.htm) the TI-2500
DataMath came out in 1972. And the SR-10 came out in 1973.

Certainly more _fun_ than some of the films that have been released for
sure! The wife will not agree though. But if one of us had a large old
S/360 or S/370 in our basements, the power consumption would financially
kill us (because of the water chillers for cooling, current consumption of
older technology electronics, etc.) I'd love to even _see_ a large S/360
and all its utilities.

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).

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!

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. It was released at about that time - I grabbed some
marketing leaflets which I believe I still have - and I thought it
looked an interesting system, but I never saw one :-(

I'll have a look in my marketing bumf and see what IBM were offering.
Alas, I have little of a technical nature.
I'd think a 9370 ought to run Phoenix/MVT at least. Do any of our
Cambridge (UK) contingent want to have a go?

You know, that sort of thing _might_ be in the marketing stuff (as in, a
complete system need consist only of...) since the main selling point
was the small size and no need of special machine room.

30A at 230V is around 7kW - running continuously, that could keep a
small house quite warm. (Typical electrical domestic heating
installation in UK, four storage heaters rated at between 2kW and 4kW
each, heat up for 7 hours at night, release heat slowly during day -
equivalent of 3 to 4 kW continuously)
Will tell the list anything more on this machine if any interest.
Yes please.
Philip.
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 $$?

No one's mentioned the problem that you'll also need to convert
the *data* once you've moved the *files*. Which word processor
created the files, and which contemporary word processor do you
hope to use them in? 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 $$$.
Of course, you'll need to run 22Disk on a PC equipped with both
5 1/4 and 3 1/2 floppies, then move the files to a 3 1/2 PC disk, and
the Mac can read them as-is.

Right - and it's fast, and the readout is visible in any lighting condition

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.

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?
Thanks,

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.

One problem with that is that the average centronics connector is wider
(thicker?) than the standard PC slot allows for. I believe this may be
true of Mac slots as well.

I have a Kennedy 9400 drive here (Gloucester, MA) for the taking. 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.

25 and 30 are ISA, anyway.

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.

It is -- vary well done! There are still people interested in them...I
didn't know there were so many slipsticks around!
(btw, I bought about 10 at an auction awhile back...still have a few left,

First of all, did MS Xenix run on PC hardware?
Secondly, was there ever a Windows NT 1.0 and 2.0? How did they compare
to a cheap version of UNIX?

It is interesting that many of the error messages in the pre V3.1 beta releases
referred to OS/2. Maybe it was an almost clean room.

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.

<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.

Hmm, couple of misconceptions there. 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.

Ok, if Xenix runs on PCs, does anyone have a copy they could send me?

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.

I have my 10" white aluminum pickett handy and grab it when a quick

wind correction. That one is in the plane as I'm absolutely certain

Hi. There's this guy, in Bahrain, who's got a PS/1 386 2MB RAM, that's been

want to know what it'd be worth, too. (There's going to be arguements....
I'm sure.) Anyway, condition is currently unknown, but assumed in working

Dollars, please. C'mon, I'm not THAT far away. (PS-The guy's here now...
might be handy.)
