Pin 1 joined to Pin 6, one side of 8.5V AC Red
Pin 2 joined to Pin 7, other side of 8.5V AC Black
Pin 3 14V AC Yellow
Pin 4 0V White
Pin 5 14V AC Blue
The two 14V AC windings form a centre-tapped 28V winding, which
according to the label on the transformer is rated at 250mA. The
8.5V winding is rated 1.5A. The actual voltages I measured were
8.9V and 14.3V (twice), so they're slightly higher off-load. The
9-pin 'D' connector on the end of the PSU cable is a female. The
PSU itself is clearly just a transformer in a white plastic box.
Thanks for the infromation. I've got much the same problem (a Dragon 32
less the PSU brick) so sometime I can get round to making one. It's not
urgent (I have plenty of CoCos), but I do like to have my machines
operational.
