Yesterday I assembled the two nodes on my Origin 200, and discovered something annoying. One of them was very dead. Since the logic appears to be getting power (even if it doesn't completely power up), and the cable is probably not suspect (each node independently confirms that one node runs perfectly fine), I'm ruling out everything but the logic carrier, which appears to be hosed.
This leaves me with a dual-processor Origin 200, and a fifty-pound doorstop for parts. Not great, but not a total loss, either. And I think it just sort of emphasizes the necessity of obtaining more current iron for an IRIX-based renderfarm. The Origin200 is 1996 vintage, and, on reflection, none of my IRIX machines break the 2001 mark.
Why don't I go to the PC? It's not a jump I'm willing to make. It will involve learning a new OS (Linux), and I feel I sacrifice far too much of my creative time to technical endeavors as it is. Migrating over to the PC therefore makes no sense to me.
