SE/30 Conquest

Posted by: FlyingToaster on 2012-03-23 15:15:40 I wanted to share my latest to my small collection, an SE/30. It boots quick as lightning 😎 but has very quiet sound.. not surprising. The ram is at 8MB and it sports the original 40MB Quantum. Very happy to own one of these finally but I have only one small issue that is buggin me. The screen looks like it's a little wavy or curvy around the top. I tried the internal adjustments but there is no setting for this kind of shape. It must have warped somehow over the years or it took a big fall? I doubt the falling part (case is great) but it would be cool to fix this.. Perhaps this SE/30 Mobo can be switched with my SE Dual Floppy?

Posted by: FlyingToaster on 2012-03-24 06:28:26 I brought out my iMac G3 and put it screen to screen with the SE/30. When I turned the G3 on, I saw it degauss the little screen. I thought it worked for sure since the screen contracted. I repeated it several times and it still is the same shape. Maybe I need a real degaussing wand

Posted by: zuiko21 on 2012-03-24 09:22:35 I'm afraid that you need to degauss the electron gun (as tecknight indicated) around the CRT neck, not the front of the screen -- that could help with colour CRTs because of their shadow mask; but B&W tubes are "empty" at the front. Placing the iMac CRT close to the SE/30 will deflect the electron rays, but won't (de)magnetize anything in a permanent way.

Posted by: FlyingToaster on 2012-03-24 11:36:05 For kicks I tried facing the imac screen against the CRT neck and it did the same little flicker during the degauss, still crooked. Bummer!

Posted by: techknight on 2012-03-24 11:57:11 use an old soldering GUN. not a wand. the soldering gun has a large transformer in it and can be used to degauss if the parasitic magnatism isnt very strong.

Posted by: FlyingToaster on 2012-03-24 12:36:06 Thanks for the advice. I have a 45W gun I will try. Really appreciate the tips!

Posted by: techknight on 2012-03-24 13:58:46 never seen a 45W gun. most were 100W or more. its one of the type that you pull the trigger it hums and gets instantly hot.

Posted by: FlyingToaster on 2012-03-24 16:52:30 you are correct, this is a really old gun and it used to belong to my dad which I always thought was 45W (I don't know much about solder guns 😛 ) Hopefully this works and this isn't permanent.
