Once upon a time this stuff was so cheap, a little later than the (2003), because IRIX was discontinued and nobody knew what to do with all of the surplus. Something like a Tezro was always a little pricey and filled a permanent niche, but I got tons of Origin 300s and stuff like that without thinking much about it at the time. I've got the Router rack and several IR3/IR4 bricks.

LLMs actually makes retrocomputing a lot more "fun" because you can slop out things that would take way too long to do by hand for pure art and exploration.
