The latter appear to include the power supply. If that's within your budget, one option would be to ask the non-working seller whether it includes the power supply or to buy a panel and power supply. There's a power adapter for $76, but that's a bad deal relative to a complete package for a dollar less. There was a good deal on a power supply, $10+7: http://www.ebay.com/itm/PROXIMA-COLORWORKS-POWER-ADAPTER-MODEL-UP30432-comes-w-power-cord-/170975604690?pt=Multipurpose_AC_to_DC_Adapters&hash=item27cef0afd2 One ebay image shows the power supply as a Model No. UP30432, P/N #400-00018. There are other power supplies online for sale; for example: http://www.kpsurplus.com/buy/power_supply_up30432_5vdc_3_0a_5vdc_300ma_12vdc_2a/58824 Another Ebay image shows the power specs on the panel as +5VCDC/3A, +12VDC/2A, -5VDC/0.3A. Pretty much any PC power supply can feed that current at those voltages, and cobbling together an adapter between the connectors wouldn't be rocket surgery. 1/2 :-) The pinouts are here: http://myplace.frontier.com/~yub_yump/Pinout%20pin%20outs%20power%20supply.htm Here's a page with a write-up on using an AT power supply for a similar projector. I didn't compare the pinouts, but it's very likely they are the same. Even if the exact pinouts differ, the concept is the same. A more modern ATX power supply should work, too, with adaptation in pinouts. http://www.realm-online.com/eovation.htm The connector on the projector appears to be a DIN-5, which should be available at any good electronics house--and maybe, just maybe, at Radio Shack. I probably have one if you can't find one and want to go that route. HTH -- Robert Riches spamtrap42@jacob21819.net (Yes, that is one of my email addresses.)
