The Proteus AC adapter is no longer available. When looking for a replacement, here is the information you'll need:
Voltage: 7.5v DC
Current: 200mA (or higher)
Tip: 3.4mm Diameter Outside, 1.3mm inside, center negative
See pics below. The replacement one does not need to look like this, but the plug and voltage need to be the same, with center negative polarity.
