Thanks!

Yes, web comments imply it's iffy for the mac.

THanks so much for the info...

The broken circle will have the line going from the centre dot
outwards to either the + or the -. This is to describe which polarity
the pin in the middle is, which is vital for not blowing it up! Have
another look? Eg (ASCII circles are hard!):
,-,
+ --o| -
`-'
for positive pin, or
,-,
+ |o-- -
`-'

for negative.

Cheer - Jaimie

Heh - oh right! Positive pin.

I truly had no idea any of this meant anything!

You are well on the way to mastering the skills of electrickery, or at
least how not to blow stuff up with a disappointing "frp" noise.

So! Now all you need a 12v power supply that can deliver 1.66 amps or
more, with positive pin and the same shape head as the scanner wants.

Even if the Mustek power supply is positive pin and physically fits,
at 17V it's rather high. This'll push the voltage regulation circuits
on the big scanner rather hot. It'll probably work, but not
necessarily for very many days... and it'll be the scanner that gives
up the magic smoke.
