Two broken (always on) power switches? Actually I remember
europlusses with a replacement toggle switch from years ago. Might
be a common failure if it's happened twice to you as well.]]>2016-02-10T06:56:04-00:00Re: Apple II+ PSU

Use a continuity tester to test the switches when both on and off. Do I need to state the obvious, make sure power cord is unplugged.]]>gids.rs2016-02-10T17:55:39-00:00Re: Apple II+ PSU

The power switch is pretty easy to replace--and the occasional need to
do so is a good argument against cycling the power to re-boot. ;-)

But the lack of an open-apple key makes it tough to really get in there
and reboot hard, especially with tricky/nasty reset hooks.]]>David Schmidt2016-02-14T06:55:54-00:00Re: Apple II+ PSU

An Apple II+ was my first computer in 1983. After a few years of power switch reboots, I soldered a switch from the NMI to ground as a bailout button (and for software cracking). I've just reconstructed a II+ from parts to re-experience my past and now am worried about wearing out my power switch so this time it's plugged into a power strip :)

The Kensington System Saver and equivalents are really nice for this, one handy power switch for the complete system with surge suppression and additional cooling, all in one.]]>Howard Poe2016-02-15T22:17:59-00:00Re: Apple II+ PSU

Yep--that's been my solution since I used a ][+. ;-)
