You can transfer files to your m100 using a serial terminal program, a usb
to serial adapter, and a null modem cable.

Once the file is on your m100 you can save it to floppy if you like.

If you have a floppy driver or rom loaded already you can use that to load
files over the serial cable via laddiealpha or mcomm or dlplus.

See below for what I suspect is your actual problem, but I thought I'd answer 
this first: there is a common failure mode which seems to affect mostly M100 
displays as far as I know, not the T102.  It's pretty common for vertical lines 
of pixels reaching halfway up from the bottom or halfway down from the top to 
go blank, but they don't come back if you twist or flex anything, and they 
don't seem to be related to bad contact but rather to some bad component.  I 
don't have more detail than that as I didn't get into repair of my bad LCDs - I 
bought up a few trashy-looking M100s and salvaged their display modules and a 
few other parts.

It certainly sounds like it, based on twisting causing the dead lines to 
re-appear.  The way that the panel connects to the PCB is through a pair of 
what appear to be translucent rubber-like strips (IIRC - it has been a while 
since I had an LCD apart so I might be wrong about them being translucent).  
This is quite common with LCDs except the strips I am more accustomed to seeing 
are made out of alternating black and white segments, so it's easy to see that 
they have conductive and non-conductive sections running through their 
thickness.  The LCD is precisely aligned with the PCB, which has conductive 
pads on it, and these strips conduct through to the (nearly invisible) pads on 
the LCD panel glass.

The LCD panel is clamped to the PCB by a metal frame which surrounds it and 
which has small tabs which fit through notches in the PCB and are bent over to 
secure it in place and apply continuous pressure.  If you remove the LCD 
assembly from the top case, you can put a little extra pressure on different 
spots around the perimeter of the LCD by squeezing the top of the metal frame 
down against the PCB with your thumb and forefinger.  Firm pressure, but not 
too much - remember it's glass.  You should be able to find the magic spot 
where the problem is happening.  If you're lucky you might be able to bend the 
tabs nearest to that spot to increase the pressure and resolve the problem 
without taking it apart.

If you're not lucky, there might be corrosion under the rubber-like strip, and 
you'll need to disassemble it and clean it... it's possible, but tedious and a 
bit risky.  I'm not going into detail on that now because this email is already 
getting a bit long.  :)

Yes, the fishpaper is in place and intact.  The fault is 
definitely on

the LCD assembly.  If I lift it out, so it’s vertical, but still
connected while the machine is on, gentle flexing of the board 
causes

the problem to appear and disappear.

Stay away from tape, play straight to your m100 or use an mp3 player for a

Subject: [M100] Dead lines in the LCD

I just got a 102 off eBay today.  It was sold as working, but 
arrived
with four dead lines in the LCD.  They’re horizontal, from the 2nd
row, and repeat every 16 pixels.

I opened it up and it worked fine.  I figured it was the cable, so 
I
sprayed some DeOxIt in there and put it back together, only to 
find
the problem was back again.  Taking a closer look, there’s 
something
making marginal contact on the LCD board.  When it’s flexed 
slightly,
the lines vanish, and the case presses on it just enough to make 
the
problem crop up.

It felt like a bad solder joint to me, but after inspecting every
connection with a 20x loupe, I didn’t see anything obviously 
wrong.  I
suppose that still might be the case, since it’s awful hard to see 
the
tiny SMD joints, even at 20x.

Is there a common failure mode for these panels or something else 
I
should be looking at?

Based on my reading of the schematic and tapping around, I 
suspected
M11 might have a marginal connection, so I resoldered all its legs 
--
still nothing.

I don’t see how the panel itself is connected to the PCB.  Perhaps
there are pads on the top side and it’s simply the friction of the
panel sitting on the board that does it?  The more I poke around, 
the
more I think it might be the PCB to panel connection.

Any suggestions on what to look at to get this machine 100%?
