I'm primarily in the business of proving conceptual designs can be made
workable. To do this, I usemultiple SBC's and various ways of communicating
between or monitoring them in order to measure and control the progress of the
tasks without interfering with their progress. I've found it's easier to set
up a single PSU with its switch and a dedicated reset button for each SBC
rather than wiring up a complicated harness for each installation. That way I
can focus on the complexity of the task and won't have to worry about the
complexity of the power distribution harness. Unlike many small PSU's, the
Apple][/IIe PSU has the four voltages I'm likely to use, AND it costs about
$3-5 to get one in functional condition. I keep a small meter with me so I
can make certain it works when I'm out "Thrift Shopping" so I can measure
the
outputs.
I suppose I could ask the guy in the store whether he'd sell just the PSU for
$1 and take the $1 off the price of the Apple ... I'm not confident they'd go
for that, however. Comparable PSU's cost $15-$25 on the used/surplus market,
so they keep me happy. These apples are not harmed in any way. If you want
one for parts or a spare, or whatever, let me know and they're yours in
whatever number you want, up to what I've got, of course, for the cost of
freight. Some of 'em are in really good shape. It's a shame, I know, to
waste 'em, but otherwise they, and their PSU's end up in the dumpster at the
thrift store, and they don't let me raid that.
Anyone who wants to "rescue" a PSU-less Apple ][ or IIe should contact me off
list from time to time. I'll package 'em for you but you've got to pay the
freight (via USPS) up front.

While that offers an attractive option, aside
from the monitors, which

Apple]['s with the PSU still in place down in the pit.
It will work better now that the weather's more pleasant, because I'll
be able to toss 'em in the dumpster and bring only the PSU in the
house.
What exactly do you need that many PSUs for anyway?
I would think that I'm not the only one here on the list who is stating to
feel offended by your bragging about butchering and dumping perfectly good
systems. If you are going to continue to scrap Apple gear, thats your
choice, just don't talk about it here.
