Joshua,
Welcome to the ModelT list. There are many more qualified and experienced
members than I, but I will try to help. If you have already removed the LCD
screen assembly, you have already dealt with the plastic cover that is snapped
on to cover the LCD ribbon cable, and you have released that ribbon cable from
the LCD screen assembly’s compression connector. With the ribbon cable
disconnected, there are only screws (4 I think) to remove to allow the LCD
assembly to separate completely from the base/top assembly.
As you noted, the four screws on the bottom of the T200 need to be removed.
There are two “halves” to the machine: a beige top and a black base. During
assembly, the top is snapped down onto the base over molded-in plastic
“catches”.
The way I have gotten the top off is to use a 1” wide blade putty knife. I
slip it between the top and bottom and move it so as to “lever” the top away
from the base (out, not up). Do not use excessive force when prying. The top
has to flex outward only a little bit to release the catches allowing it to be
lifted off.
Sometimes I have had to do this maneuver on the other sides as well. For
reasons that I cannot remember, I usually start prying near the middle of one
of the sides, not the front or back; but this may not be important.
I also remember having used a flat screw driver blade as my pry bar. Usually
the thickness of the blade inserted up under the top about 1/8” is sufficient
to move the top away from the base and allow it to release.
I hope this helps! Good luck!
Bob

Subject: [M100] Tandy 200 repair, guidance requested
Hi all,
I'm new to the mailing list. I was referred here from the vcfed forum.
I have a Tandy 200 that needs some help. The power key is damaged and
disconnected from the keyboard. I have a pdf of the service manual, and I'm
trying to disassemble the device so I can check the internals and reattach the
power button if it is serviceable.
So far, I've removed the monitor and the four screws holding the bottom case,
but I'm encountering a lot of resistance when I try to remove the top half of
the case. Before I damage something, could anyone tell me if I've missed a step?
Some forewarning: I'm a newcomer to vintage computing, and I only have basic
electrical experience. I've got to start sometime though, and I'm willing to
learn.
Any help you can provide me will be appreciated!
By the way, if you need me to attach pictures how do you guys usually handle
images on this mailing list?
Thanks!
Joshua.
