Hello there!
I have a newly acquired 128 with a flaky PSU. Can I use a 9V/3A PSU from an
Atari 1050 floppy drive to power it?
Thanks,
Frank

looking at [url]http://www.worldofspectrum.org/faq/reference/hardware.htm[/url],
the 128k needs 9v at 1.85 amps, so that power supply will be fine.
make sure you have the right polarity on the plug though! The centre is
NEGATIVE. the barrel is POSITIVE

That's a problem! The Atari power supply is AC! You may see smoke if you
try it.

You're right, I've just checked. Well then, I'll better keep my hands off
it. (-;
Thanks for the heads up!
No, I don't think so. I'm not even sure the polarity is the right way
around.
I know some of those Atari psus just gave AC out with the rest in the unit
but Do not recall if this was one of them.

But usually a flaky 128 supply was just the lead in any case. Very little in
there to go wrong otherwise.

Why not use the lead to replace the faulty one on the Sinclair?

You are right, Brian, it's the lead, just where it "leads" (sorry for the
pathetic pun) into the case. Maybe just a loose connection. I'll check it
later this week.
Thanks,
Frank
I've just checked: the power brick I have (the one with the flaky lead)
throws out 13.9V. Is that normal?

If that's 13.9V with nothing plugged into it - yep, that sounds right.
Spectrum power bricks are unregulated, so the voltage drops when a load
is applied.
