just curious if anyone here knows much about slotted imac g3's hardware
probably doesn't pass the apocryphal "10 year rule" but it just might.
(that's a joke. no flames about the existance or non-existance of the any
rule, real or imagined)
Anyway, I've found a few "slotted" g3 imacs with dead power supplies. There
are some web sites which talk about case conversions but they all refer to
the older, earlier imacs. One talks about the slotted g3's but its in french
and doesnt' speak to my issue (it's a nice site, however - merci!)
I pulled the logic board out of the case and I want to power it. It
looks like the PAV (the big power supply for the crt) provides 24VAC to
the main board and there is a switcher glued on to the logic board which
makes the +5,3.3, etc.. It's just that the wires which seem to feed the
24VAC seen very small. They do lead (across the entire pcb) to the
switcher connector and those seem to lead to a transformer, so I think
I'm on the right track.
So, I'm looking for confirmation - is the logic board on a slotted imac
g3 powered by 24VAC to a local switcher and are those 4 wimpy little
wires supplying the ac? the French site labels them "24VAC phase 1" and
"24VAC phase 2".
No sense replacing the switcher if it works.
I thought I'd find a clear box for the motherboard and my kids would
oh, and if anyone has a "marathon irack dv" box they don't want contact
me via email.
