Re: Apple IIgs random hardware crashing - any ideas?

[Ed Eastman <ed@apple2.com>]

Try the simple stuff first:

If you think the shielding may be an issue,pull the shieldling out of 
the case and run your IIgs without it.

Try a heat gun/hair dryer and see if you can make the board fail by 
heating specific areas the same way you attempted to locate problem 
areas with the freeze spray.

I concur with Michael.  It is probably a stress induced by the being in 
the case.  Physical stress laterally along the board, probably combined 
with a minor heat up to emphasize a crack in a trace or cold solder 
joint.  As video is messed up, I'd check the 'slow ram' for solder 
cracks first and concentrate on testing the board in that area.

Thankx,
