SE/30 Conquest

#1 Fri, 23 Mar 2012 - 22:15 68kMLA

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?

your electron gun has become magnetized.

you must degauss the electron gun of the CRT.

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

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.

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!

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.

Thanks for the advice. I have a 45W gun I will try. Really appreciate the tips!

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.

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.
