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...
Yeah, come to think of it, I do seem to recall swapping a number of A2
PSU's back then. That was before I was willing to try component repairs,
so it was simple swaps of bad for good.
