How often did you run this machine? Dirt buildup on the contacts leading to more resistance in connection?

It’s on at least 12 hrs. everyday. 

I assume it was micro arcing, which leads to carbon, which leads to more arcing, more carbon, more arcing.......

It’s not dirt buildup, the interior is spotless..

As a matter of fact, it’s on now..

Yes. Thank you. If I can, I’ll let everyone know how & where to get parts, which not everyone does, but should.

Ok, I gotta ask... why? I mean, dumb question to ask on a Compact Macintosh forum ("because I can!" is the whole reason this forum exists).

The 512kE is my room clock, and I have files with my passwords on it..

I also use the SE/30 for midi.

The G3 as a tech bridge.

I have never owned a new computer, and just don’t have the need for one, and don’t want to “chase technology”.

i don’t play games, or do HD A/V processing. 

I have a new MacBook at work for A/V, that’s enough for me.

My home daily driver is a 2.26ghz 2009 white MacBook, and the 2017 iPad I’m using now.. I guess the newest piece of tech I have is the iPhone 7 Plus that my boss gave me.
