I picked this beast up for cheap... no real use for it, but I'll eventually get it going as an end table in my basement!

BTW, does anyone know, of a media converter for the front that will actually let the door be closed?

IRIS 57# who

100 MB ethernet seems crazy expensive for this box??

Don't let my remarks turn you down. Challenges are fun boxes, but the learning curve can be steep.

Ha, I'm not turned down. The machine is hilarious when its running. Irix just feels different than Linux/AIX etc...

Is there any way to determine how all the SCSI is wired in it?

Ie how to find out, if its HVD?

Hi

2 questions --

1 - Is it possible to load some graphics onto the DM? I was looking inside today to sort out the types of SCSI, and it seems like there is lots of space to put graphics ?

2 - Does anyone have some part #s for FDDI boards??
