> I wonder where all those machines ended up. Would love to get one and play with them. A lot of them (probably the vast majority) simply got dumped, alas. I personally decided to dump a Challenge (basically an Onyx without the Reality Engine graphics: https://en.wikipedia.org/wiki/SGI_Onyx https://en.wikipedia.org/wiki/SGI_Onyx). As in: I could have it if I wanted it, I used it for years but it had to go when it was obsoleted. I could have put the rack in my basement, but I'm not young anymore and it wouldn't be that many years before it would be a headache to get it out. So I said: "Sorry. Dump it." Smaller is more manageable of course - I have a number of O2, O2+, Indy computers and an Octane. And a Fuel. At work we had a bunch of Origin servers as well. All dumped. Back to the Onyx - when it came out in 1993 I had some access to one, I worked in the same computer room for weeks at the time on an off. Played with the various graphics demos, mostly. But I watched what the guys were doing with it. It was very impressive, a huge step up from anything else, and the sheer performance and memory bandwidth of the thing was one big reason I argued for getting an SGI Challenge for a later technical project. And I was right on that, as it turned out. Nothing else could do the job at the time (in this price segment, at least). As for the CPU speed - Like the R4000, the R4400 internal pipeline ran at a higher rate (internal multiplier): https://www.cpushack.com/MIPSCPU.html https://www.cpushack.com/MIPSCPU.html
