[M100] M200 power issue

[David Anderson]

Hi all,

Before I dive in the M200 troubleshooting process, I thought I'd check 
to see if anyone else has experienced this. After many years, I'm the 
happy owner of a 200 again. I've replaced the NiCD already.

It worked a few times... but now just shows two horizontal lines across 
the screen. When I try to power it down, it's doing something but 
doesn't actually power down. I can hear a faint noise as it struggles, too.

I'm guessing (having read the troubleshooting procedure) that I'll need 
to replace some old electrolytic caps, given that they're 30+ years old.

Has anyone else seen this behavior? Anything in particular I should look 
for?

Thanks!
David

PS. I started in the M100 world years ago with a Kyocera KC85 I bought 
from DAK (I think). If you're an old Compuserve user, you may have run 
across the ROM dump I uploaded in the late 80s. I used to have a full 
200 setup w/ disk drive and other accessories but it disappeared over 
the years. Looking forward to getting back into it: I want to try 
interfacing projects via the system bus.
