Would it be possible for you to show the DIN connector and measure what voltage is on what pin?

I would like to fit a DIN plug to mine but I am not sure what is on what pin.

Thanks

The post by Bloodnok earlier in this thread should be what you are looking for.
Unfotunately I don't have a multimeter to perform a test on the PSU I've got. But I'm willing to buy one soon, so until then...

Hi there,

I am not to convinced about that pin-out as it talks about 18V AC and 11V AC where our PSU
has a 15V AC and a 9V DC.

Thanks

Yes, indeed. I was very dubious too when I saw that picture, but the guy at RWAP Software kind of confirmed that picture was taken by the tech manual of the MicroP Disk Drive.
As soon as I have a multimeter ready to go, I'll send you the voltage of each pin, but it could take a while, maybe a month or so.

Did we get anywhere with the pinout for this?

15vac and 9v dc

Thanks

Russ

Tonight I measured the voltages out of the official PSU on the 4 cables that are showing,
as on mine the 6 pin DIN plug is missing!

I got the following:

Red - Green 16.2v AC
Blue - White 9.9v AC

SO my only assumption is that the label is not telling us the whole truth and the earlier
wiring diagram IS CORRECT.


As for the 5 pin DIN on the SECOND floppy it goes as follows:

1 - 5v RED
2 - NC
3 - Earth BLUE
4 - NC
5 - 12v YELLOW

GREEN WIRE NOT CONNECTED
