The site www.reputable.com is for a used equipment dealer (no affiliation, but I bought my I2 from them), they have lots of really good links. In particular there is a multi-page SGI FAQ that will answer 70% of your questions. If I'm not mistaken the serial is RS-422 like on the older Macs. I'm not sure if the pinout is identical or not, but you can get a matching connector in the Mac section of CompUSA and re-wire the other end if you have too. The audio connectors are like a standard PC. The keyboard and mouse appear to be standard PS/2 variety. Amazingly, I even had a QueCat and hacked Linux driver for it working under Irix when I played with that durring its ten minutes of fame. Mine is an extreeme, but I suspect your Impact uses the same identical 13W3 connector, DB25 shell with 3 mini coax inserted with a dozen or so regular pins. The video will be sync on green. There's some comments on the reputable site on what it takes to get some monitors to use that. There's a small flat connector near the audio that has lots of really tiny pins in it. That is the external SCSI. This should get you started. If you have any other general questions, email me off list and I'll point you in the right direction. -- J.
