I had an Xeye recently without the power supply. Having read that it's hazardous to use a Genesis power supply with the Xeye, I was hoping to find a compatible power supply. Unfortunately, finding one with both the plug and the specs is very tough. What I did discover in digging around my Goodwill Computer Depot was that there is a power supply that has identical specs, but a different plug style, than the Xeye.
Apple's StyleWriter Power Adapter model M8010 (for use with model M8000) has these specs, which match the Xeye:
Input 120V 25W 60Hz Output 9.5V 1.5A.
It is a large beige power supply if you are looking for one in the thrift store bins. I have not spliced the proper plug onto it yet, but it should not be a very big project, even for an electronics luddite such as myself. I would love to hear some input about this finding.
