Re: Apple IIe and Profile (Power supply burned out?)

[cjyo@my-deja.com]

I did play around with the II+ mini-pot, but it never got rid of the
lines completely.  I also tried it on two monitors with the same result
(bad).  For the 2 hours that my dead IIe was running, the same monitor
(Apple Green mono) was crystal clear.

It is usable, but I don't know for how long.

I actually think the power supply on the IIe is fine now.  After more
advice and careful inspection it seems okay (and the fuse is good).

I think I will take your advice and try only one hard disk/controller
at a time, when I can get the (or another) IIe running again.
