    Default Creating ZX Spectrum +2a (Black) PSU From Desktop PC ATX Power Unit

    I have a couple of old working Desktop PC Power Units and have just bought a Spectrum +2a (Black) without a psu.

    I have read a few bits on the net about creating a PSU for the +2 using the PC Units. Any advice anyone could give me would be most welcome.

    The Spectrum takes 9V so it would be less work to just get an appropriate power supply on-line.

    Sorry, I'm an idiot. I see that the +2 and +3 take 5V, 12V and -12V. First two would be easy as they are readily available on any 4-pin molex. I don't know about -12V.

    It looks like if I use the wires from the 24 pin that goes to the motherboard, the blue on that is -12v

    you can take advantage of those cheap and common Cisco router power supplies people use with their Amigas.

    I was gonna suggest that but since he already has an ATX power supply, might as well use it.
