Replacing CRT in eMac?

A few weeks ago my school threw away about 200+ computers. I found a couple of useful things, including an eMac. Never having owned a mac, I brought it home. I quickly discovered, however, that the CRT is broken (hence why it was being thrown away). I looked on google but couldn't find a guide for replacing the CRT in an eMac... yes, I know it is dangerous.

Thanks

Salvage the parts, it's probably not worth it to try to replace the CRT.

What if I have a bunch of old CRTs lying around? It's not like replacing it will cost me money. I was wondering if emacs were like imacs, where you could actually just open them up and unplug the built in monitor and then plug in your own?

Here's a documentation of the eMac's guts:

You might want to replace internal CRT with a nice cheap 17" flat screen and keep eMac in its original case. Maybe add and extra internal hard drive or two. This will need solving two problems - mechanical, including enlarging the fascia opening and power-related. Yes, CRT can be removed and all high-voltage circuits disabled. However analog board uses CRT vertical sync signal to control its power supply so without it all the voltages tend to sag under load. It is solvable of course but I just did not look at it (yet?)

You would be the first person to exchange the CRT and document it on the web! :) However if you don't have the same model than the person who wrote the documentation, your logic board might be different.

To identify your eMac, try Apple History, or the program System Profiler if you can use an external monitor yet.

The guy has some more eMac tinkering ideas on his website.
