About the message about OS/2, "Which is the minimun configuration for
running OS/2?"
I have heard that you need a 386 with 2 or 3Mb at least. More to the
point I have a 8MHz 286 with 512K of mem and another 512K of extended
mem.

Subject: AT bus drives
The AT-Bus drive, also known as the IDE drive, is designed for optimum
performance/value for AT (286) and better (386sx,386dx,i486) systems.
Essentially they include the normal interface for the PC on the drive
itself and the controller card you use is really basic - little more
than a connector from the drive to the bus via one of the slots.
Many manufacturers are offering IDE versions of their drives at really
good value - for instance the Seagate ST-151 40MB IDE drive which is a
great buy.
I note you are using COHERENT; I am new to this list - are there many
people using it / how well does it work / is there s/w available on
BITNET for it? (I ordered it a few days ago and am looking forward to
playing with it).
Cheers,

Subject: Re: Hard-Disk Spins at Half Speed
In reply to a message about someone who wanted to know how fast their
hard disk should be rotating. Someone else responded that a hard disk
should spin at 3600 RPM exactly.
This is true, but remember that SpinRite may not report the speed
exactly. I have an ST-238 that reports a speed of 3600.8 RPM, but I
also have used SpinRite II 1.1 on an NEC Multispeed HD laptop that
reported about 1800 RPMs (I believe...hard to remember..the important
thing is that it's REALLY far off of the theoretical 3600 RPM). Here's
the reason: SpinRite also reports that the NEC's hard disk uses the
ARLL encoding scheme. I suspect that this fools SpinRite into thinking
that the RPM is way off. (I assume that the hard disk is still
spinning 3600 RPMs like it should)

When you have the Extended Edition and want to use the communication
manager and the database manager you'll need at least 5 MB to run it
smoothly!

I've been using UNZIP.EXE on the vax and don't know how I could have

Subject: BIOS-Problems with disk
Hallo Networkers
I've got a problem with a AT-Clone. We want to install a 60MB Harddisk
into this machine. The disk has a type of 47 which means 965 Cylinders
with 5 Heads and 25 Sectors. The BIOS of the 286-Machine doesn't
support such a type of disk. Are we able to read out the BIOS change
one of the free locations in the setup table to our value and write it
back into a new EPROM.
Or is there any other chance to get such a drive together with a Compaq
multipurpose fixed disk drive controller Type 000957 running in a
AT-Clone? But we want to use the complete disk with 60MB's. A try with
diskmanager only allows us to use the drive as a 42MB disk. Many
thanks in advance.

Subject: EMS 3.2 -> 4
Hi there,
I have a LASER Turbo XT-2 with onboard expanded memory. The driver i
got with it is for EMS version 3.2. (EMS = Expanded Memory
Specifications)
To use this expanded memory with MSDOS 4.0 however, i need EMS version
4 (LIM). Is it possible just to use a newer version of the driver, or
are there also hardware changes between version 3.2 and 4 ?
Where can i find a driver for EMS 4 ?

Has anybody had any experience with a board produced by the company
"THE COMPLETE PC", the board I am refering to is called the "COMPLETE
COMMUNICATOR". Basically has anyone ever used it, and what they feel
about. How does the 3 operations work together, can none technical
people use this board (calling in). If this not the place for this
type of question can someone refer me to the correct one.
Thanks for your time...Bill

Subject: Info on CAD and/or CAM Systems
Hello,
I am looking for a CAD/CAM system with the following capabilities:
- draw wireframe models of 3D objects
- run on IBM PCs/Macintoshes/Workstations (any of these platforms is OK)
- allow boolean subtraction/addition of solids
- macros/scripting
- libraries of objects
- render (solidify) them relatively quickly (not totally necessary at the
moment)
If you know of any commercial/research software with these
capabilities, or have comments about CAD systems that you have used, i
would love to hear from you.
Thank you in advance,
Gordon

Subject: OS/2
Hello,
You can run OS/2 (1.1 or 1.2) with a 80286/12 + 2 MB of RAM; I mean it
will run but you will find too slow (too much swapping !). For the 1.x
version (they run the same whether you have a '286 or a '386, you must
have a minimum of 4 MB in order to avoid swapping. It is running very
well like that. Except for speed you have no gain with a '386.
Hope that helps,

Where can I find source code for a PD modem (terminal emulator)
program for my PC clone? I want to be able to customize a modem program
to translate and output some ascii key codes into different values or
sequence of values. I have C and Fortran compilers. (BASIC is just too
slow). Any help would be appreciated. Please send replies to me, and I
will summarize for the list.

Subject: Connecting PAL TV to a PC?
A friend of mine would like to hook up his color TV (Pal system) to his
PC, and was told there is a card out there that will do the trick. CGA
resolution will do (though I suppose super VGA would be even
better....). Pointers, anyone?

Subject: Suggestions for PC Anti-Viral programs.
Hello, everybody.
I manager a lab with some 25 IBM PS/2's at a small college. The
machines are primarily used for standard word processing, spreadsheet
work, and the like. Up until now, life has been pretty peaceful.
However, the age of the PC virus has arrived. I am currently fighting
off an attack of the Ping-Pong virus, and am not having much luck. What
I need are suggestions on the best way to keep a room full of PC's
virus-free. Particularly valuable would be names of programs that act
to prevent the machines becoming infected in the first place, as
GateKeeper and Vaccine do on the Mac.
Please respond directly to me, and there seems to be interest, I will
summarize the responses for the net.
Thanks!
