The plug is the same, but connections are different. GND is on different
pins too. He will blow up his SAM or the PSU or both.
It will definitly not work. Technicaly impossible! If you like the smell
of burned electronics, test it yourself.
Spectrum+3 PSU has 2x+5V, -5V, 2x+12V, -12V
SAM has +5V, +12V and outputs to the TV modulator build into the PSU.
It is possible to modify the +3 PSU to supply SAM by changing the
connections.

hi Jonathan,
I can supply you with the data of original Sam Coupe Power Supply:
5 volts DC, 2 Ampere
12 volts DC, 0,1 Ampere
compare that with the Power Supply you got, if the plus 3 Power Supply
has the same data then its technically ok to use it, but the Power
Supply plug on computer side is probably different. Sam Coupe has a
standard DIN 5 pole plug. Check your handbook on page 173 for the
data. If the plus 3 Power Supply has higher than a 5 volts DC supply,
then its not ok to use it though (might be the case, as original ZX
Spectrum has about 9 to 12 Volts DC Power Supply).

Hi.
I have a question about the sam coupe power input. Wasn't sure
where to ask it so I thought I would try here
A while ago I bought a sam coupe on the net. It didn't have a
power supply but the seller said that a spectrum +3 supply works
with sam and sent one along with the it.
For one reason or another I hadn't got round to trying to test it
till yesterday. The problem is I don't want to plug it in until I
know that this power supply will work.
Could the spectrum +3 psu possibly supply the sam with power ok?
Thanks for your help.
Jonathan.
