I picked up a Sun SPARCstation IPX at VCF SW, and I'm having trouble getting the computer to power on. I recapped the power supply, and it started up once when sitting upside down connected only to a hard drive, but after connecting it up to the IPX, it flickers the power light for a moment and then turns off, refusing to turn on again until it sits unplugged for a bit. The IPX doesn't seem to have any shorts. Any ideas on where to start troubleshooting? Thanks!
