When I posted on this subject last month, I received a reply from Scott
Bruck who works at the Matsushita Display Technology Research
Laboratory in Osaka  (sbruck@em.drl.mei.co.jp)

Regarding FSTN (film compensated super twisted nematic crystal displays)
he said, and I quote, "no there are no particular color combinations
that will affect the reliability of the LCD display. It may, however,
create nearly unreadable displays!".

(Out on a limb here -- I am not familiar with the CMS tape drive -- but I

This is probably a limitation of the software.  Tape backup units typically can
overwrite sections (perhaps with "fuzzy edges" where they start/stop, depending
on the precision of the transport mechanism).  But consider this: if you want
to keep the data *after* the volume you erase, you can only store something
that is the same size or smaller than the volume you overwrite.  This is 
because few, if any, tape software allows fragmenting of data sets...

 I have a perplexing problem (at least to me it is) and I was hoping
 somebody out there has run into a similar problem and solved it.  I
 have a Compudyne 2400 baud fax/modem (internal) installed in an AT machine
 I built myself.  Recently, I've run into this problem;  when I go to
 dial out, I can hear a dial tone for about 5 or 6 seconds, but no familiar
 touch-tone dialing.  After 5 or 6 seconds, the dial tone is lost and
 the message "NO DIALTONE" comes up.  At first I thought the problem
 might be with my CD-ROM driver.  This had caused problems previously
 and I thought this might be the problem.  Unfortunately, after booting
 with relatively "clean" boot disk (I have a mouse driver and a joystick
 driver and no other boot up programs), the problem still persisted.
 The modem can answer the phone and typing AT on the command line returns
 the familiar "OK".  Both the modem and my software are setup for COM
 4.  I have a mouse using COM 1.  If it means anything to someone, the
 last time the modem worked was when I successfully received a fax a
 week ago.  I am using QL2FAX communications software.

 If anyone has any ideas on solving my quandry, I'd appreciate it greatly.

Okay, here's my question...  I need some jumper/DIP switch settings for my
I/O card.

Specifics:

Manufacturer:  SIIG (Suntek Informations International Group)

Layout: 9-pin serial and 25-pin parallel ports on card itself, and game and
serial connections to a second seperate insert.

There is one set of 4 DIP switches.  There are three jumper blocks, two of 
which have four (one might have five) positions.  The other simply has two
positions.

What I need:  The settings of the above switches and jumpers so that:

a) the 9-pin serial on the card itself is COM1.
b) the parallel port is lpt:1.
c) the other serial (10-pin to seperate insert) is COM3.

If anyone out there has this card, and can help, please let me know these
settings.  Please mail them to me, in fact if at all possible.

(Could at least one random person mail me too, just so I know this went out?)

Thanx...

OPTi is at 2525 Walsh Ave., Santa Clara, CA 95051, 408-980-8178.
To find out more about your motherboard, open the case and examine
the OPTi chipset chips.  Write down the chip numbers (might be
82C392, 82C391, and 82C206 which comprise the OPTi 386WB chipset).
When you talk to OPTi, tell them that you want technical docs for

What you are looking for is a null-modem cable with full handshaking.  This
allows communications between two computers at full speed.  The pin
configuration is as follows for the typical 25 pin RS-232 connector:

 1  -  1
 2  -  3
 3  -  2
 4  -  5
 5  -  4

     |-8
 6 --
     |-20

 8-|
   --  6
20-|

 7  -  7

(no other lines connected)

I've personnally never tried to simply COPY a file to/from the COM port. 
PC Magazine has a freeware utility called ZCOPY that when run on both
machines, finds the highest safest transmission speed (for a short run,
115K is typical), and can use wildcards to send up to an entire directory
to the other machine.  File names are automatically kept, time/date
keep/create is an option, and best of all it uses a version of XMODEM to
make sure the data made it across the cable.

Date: 2 Sep 92 01:47:09 GMT
Organization: University of St.Gallen, Switzerland

I've got a question concerning increasing the Mhz-rate.
What for is the quartz (for example 33.Mhz in a 486-33)
responsible? Only for the CPU speed or also for other parts
(chips) in the motherboard? So my question is: will there
encounter no problem concerning the motherboard by
increasing the Mhz-rate from 33 Mhz to say 50 Mhz?

And then of course the second question:
In a PC-magazine (unfortunately I can't remember wich it
was) they wrote an article about using an ice-cap to
tune the system. They suggestet to use an ice-cap for a
486/33 system and said that would allow to replace the
33 Mhz-quartz with a 50 Mhz-quartz. Is that really 
possible? Will the life-time of the CPU be reduced by
that action or will there be no problem because of the
newly built-in ice-cap? Would that be possible in every
motherboard having the quartz on a socket?

So would you agree to tune a system like this? (or not, why?)

You have three choices.  
1) Align your drive after a lot of R-ingTFM, with an oscilloscope.  It is a
   delicate and time consuming process, but can be done.
2) Buy a special diskette that virtually turns your PC into an oscilloscope
   for the purpose of drive realignment.  This special test diskette plus the
   testing software will probably run you a low(?) three figure sum.
3) Replace the drive.  At around $60 for a new drive, how much aggravation is
   it worth?  It is certainly NOT worth paying a professional to do #1.

Bottom line; if you want a working drive, do #3.  If you are more interested
in learning how drives are aligned, use #1 or #2.  If you choose #3, you can
still _also_ choose #2 as a diagnostic tool for ongoing use.
