My Model 100 keeps giving me fits. The latest issue is that after a few minutes 
the screen will start getting darker and darker until it is completely black. 
It will flicker to the correct brightness if you wiggle the knob a bit, but it 
doesn’t stay, which I am guessing means it’s either dirty or just wore out. 
To date (before this problem started, but it had others...) I cleaned the board 
with alcohol and glycerin (thanks hey Birt!), replaced the nicad battery, 
removed said battery, removed rex rom, removed and reseated nonsoldered ram 
module, recapped logicboard, and walked away from it for a few weeks. 
If anyone has any suggestions, I’d love to hear them.

P.S.  I normally post on the Discord channel, but I haven’t gotten a message 
from the list in a while, so this is also a test to see if I am still on the 
list. :)
