I can't speak for the 124 specifically, but in general, something has happened
 to your horizontal sync. From your description, it sounds
 temperature-sensitive. I suspect a bad solder joint, perhaps at the flyback or
 horizontal-output-transistor (or in those area(s)). Good luck.

        The Exact thing happened to me, and it WAS NOT THE MONITOR!
 
 
The problem really showed up whenever I tried t use a Re-set Proof RamDisk, OR
Shadow (ver 1.1)
 
Well I opened the macine up, thinkng that I was having problems with
my new Z-Ram 3-D/4 Meg upgrade, I installed recently. Well to make a long
story short, it was a pin connection on the GLUE chip that caused all the
trouble. All I did was to re-move the chip, clean all the contacts, and
then replace the chip. Bingo..... Problem solved.
 
As an aside, I also did the same to the MMU socket connections.
 
Havn't had a problem since.....

 built a switchbox. Basically you just need a 4 pole switch, to switch the RGB
 lines and mono. There's an article up on GEnie (do a search under multisync)
 that tells how to do a NEC II, the 3D is the same except it uses the 15-pin VGA
 plug, which is available from Radio Shack now. Also, I think E.A. Brown now
 sells a couple of switchboxes that may work with the 3D.

Has anyone used the Portfolio for any useful work?
Care to elaborate?
How do you transfer data from the Portfolio your PC. IBM ST?
Are you happy?
 
Thanks for any response?

A friend of mine recently ftp switcher.lzh.  However when we download it
and try to unlzh it, we get bad header messages.  If anybody has successfully
unlzh it could you email the file to me.

TeX produces a DVI (DeVice Independent) file. Another program can show this
on screen, or send it to a suitable printer.

        Stuff Deleted....
 
I went through this a little while ago, with TWO STfm's I have at my workplace
and here's what has to be done....
 
 
Follow the New Bank of Ram down towards the front of the machine. You `should
find a chip just off to the right on the way down, U68 and it should be a
74LS11N chip. If it is missing, your going to have to get one, and place
it in there.
 
The Hitachi # is HD74LS11p
 
There are three resistors that are not soldered in also, I believe there the
ones that you have made referece to. #'s R71 / R72 / & R73, and should be
33 Ohms @ 2% tolerance.
 
You machine should boot, and recognize the second bank.
 
The pad that you are referencing to are for two or six set ROM's! There are
three of them, two by the Rom chips and one by the MMU (MCU) chip. There
labeled 256K and 1M (or 1 Meg). If you are not replacing your ROM's then
LEAVE THEM ALONE!
 
There is a place on the mother board to install a Blitter Socket and CHIP,
But seeing that I use TurboST, and I have seen blitter installed machines,
and due to the type of use i am using the machines for, I have no need for
the blitter, so I have not investigated installing this. Fact is that besides
the blitter, there was (on both machines) another chip that more than likely
has to be installed if you desire the blitter upgrade in. Like I said, I
don't have the need, so I just never went any farther,
 
#include <std. disclaimer>
I have doen the upgrade to both machines, and all is well. I am a Tech,
and was working on MY OWN MACHINES! If you try this and your machine blows
up in your face, I take NO respopnsibility.
