Sam,
It should be fairly simple to find a suitable 5V power supply, but in
case you want to wait until you do some testing, you can use 3xAA
fresh alkaline batteries (or three any other bigger capacity alkaline
batteries, e.g. C or D size). Connect batteries in series, and they
will provide > 4.5V, which should be enough for the Zeta SBC alone. I
wouldn't test the floppy drives functionality using batteries.
As far as power supply, you'll need a 5V regulated (this is
important!) power supply. The amperage will depend on the
configuration - the rough calculation is: 500 mA (0.5A) for SBC, 1A
for each floppy drive. So for example for Zeta SBC and one floppy
drive you'll want to get at least 1.5A power supply. (2A, or any other
higher amperage power supply will work as well).
If you have an unused PC (AT or ATX) power supply it can be used
also...
Thanks,
Sergey

Hello,
I've finally finished constructing my Zeta board and I'm currently looking
for power supplies for it. But is there a way of testing that the board is
set up OK before buying eh power supply? I think Sergey mentioned using
3xAA batteries?
