An HP9845C, loaded, except missing the PSU.? I got it from an HP repair shop that had used it to repair other 9845C systems.? Apparently the power supply was pulled to test or repair another system, and never made it's way back.? The system is in excellent shape, but I have sadly never been able to power it up. I at one time had a deal with Jon Johnston of the HP Museum to trade three working option 100 (standard) PSU's for a working Option 200 PSU, but I was unable to repair my one faulty unit in time for his USA trip, and then my two working Option 100 supplies both crumped out.? And then, Jon's tragic and untimely passing. (Moment of silence.) Dave.
