<Stuff SNIPped>
What puzzles me is why the IMSAI folks decided to use
a switching
power supply when the box and everything else already supported the
needs
of the S-100 with the previously available and now
quite inexpensive
unregulated supplies of yesteryear.
Well, for a given wattage, switchers are smaller, lighter, and more
economical to produce. I imagine if they resorted to the old iron-core
transformers of yore, they would have had a difficult time finding
a supplier for them.
When they did, the part would probly cost as much as the rest of the
materials put together. Makes perfect sense to me.
