Looks like you set the SCSI id by changing the jumper settings. Like most jumpers, it's not altogether clear which jumper to change (although it does have the different combinations on the drive.) It plugs into the drive cable using a slot type (rather than a pin type). I'm not sure I can find a cable that will plug into it. I thought I might be able to change the jumper settings to a different setting and use an external as a master boot. I might be able to get into it that way. I suspect this is a 16MB RAM chip, as that is what is in the other machine they left the RAM in. I do think I have At Ease on one of the machines. I'll take a look at that and at doing a PRAM zap. (I can't do one with the drive in, since it has the keyboard disabled on boot.) If all else fails, I'll just do a clean install and be done with it.
