Actually yes in this area they dismantle the equipment for recycling
and send it out quickly here.
As far as a load I think I can easily hit 2 to 3A on the +12V and 2 to
4A on the +5V. Sadly wouldn't be any load on the +3.3V. Though I
probably can get another 1A on the +12V just from adding some cooling
fans to the case.
My friends system he has a (2) 5.25" floppy, (1) 3.5" floppy, Syquest
44MB SCSI, Syquest 88MB SCSI, and a 240MB Apple branded SCSI drives
and those should give a good load right there for both the +12V and
If I really need +3.3V load I can probably wire up some LED's and
resisters for the right mA ratings to get that going on both my system
Though I figure we as a large group of CoCo uses are always tasked
with trying to make newer hardware usable on the CoCo anyway. I
figured trying to figure out a good way to use a ATX PS in place of
the old AT PS project a good one :D
