The analog board from those Macs was notoriously
flaky. Lots of under
rated parts that burned out easily. Probably Apple worst power supplies.
That figures from Apple :-(
Ironically, the 2nd worst are the CRT iMacs that
brought back that same
style computer. And ironically, the iMacs are bad for the same reason,
under rated components that burned out from normal use. You would think
Apple would have been more careful the 2nd time around :-)
You mean 'at least 3rd time around'. The Apple ][ PSU is marginal, or at
least mine was. The 5V line was rated (IIRC) at 2.5A. A mainboard,
language card, disk controller, and 1 drive (i.e. not a very full
machine) exceeded that on my meter. Perhaps I was just unlucky and had
parts that took more current than normal, but I had a lot of trouble with
the Apple ]['s PSU...
