Do I get to post my hostnames?
Solarissparcgap: A Sun Ultra 1 200E Creator3D that I no longer have, my first Solaris box. Jumped the gap into SPARC ownership (although my printer is SPARC-based, too).
leydenjar: An RDI PowerLite 640 (50 MHz) that I was given. This being a laptop clone of the SPARCstation LX, it's an old way to take a SPARC with you. A Leyden jar was an old way to take a spark with you.
brescia: A Sun Blade 2500 2x 1.6 GHz, which was the fastest CPU configuration offered in a workstation-class SPARC machine. So, it was the "biggest" SPARC. The lightning strike with the biggest impact as far as death toll struck Brescia, Italy, when it hit the Bastion of San Nazaro, detonating 90 Mg of gun powder, and killing 3000. We'll call that the "biggest" spark.
Other *nixuncannyvalley: A Dell CS24-SC running FreeBSD 9.1 (runs
http://bhtooefr.org). Basically, a whitebox server that Dell slapped their logo on, to get a 2-socket, 4-bay 1U machine. So, it's a weird Dell. Weird == uncanny, Dell == valley.
korora: An IBM RS/6000 Model 250, although that has nothing (except for the size, the 2xx chassis being the smallest MCA machine with two 32-bit MCA slots) to do with the name, and it's only in this category because the host OS is AIX. It's got a P/390 Adapter/A (with RAM card) installed, which is a System/390-compatible CPU, 32 MiB RAM (and another card bolted to it with another 96 MiB), and glue logic to attach it to the MCA bus. Kororā is Māori for the Little Blue Penguin, which is the smallest penguin. IBM is commonly referred to as Big Blue. The mainframes are the biggest IBM hardware. This is the smallest possible IBM mainframe.
RISC OSriscybusiness - This was my StrongARM Acorn RiscPC. I might resurrect it (needs a motherboard) eventually.
sapling - My Acorn A3020. The A3010 and A3020 were the smallest non-laptop RISC OS machines, and were also among the slowest (there were a few slower, though). Good for games, though.
WintelKiaAvella: An Acer Aspire One D250. In the US, Ford sold the Kia Avella (a variant of the first-generation Mazda 121) as the Ford Aspire.
Ko-Hyoteki: A Fujitsu P1620. Core 2 Duo in a netbook sized machine... so a little machine that pack(ed for its time) a punch.
Ko-hyoteki means target (which was some subterfuge, in case it was discovered by spies), but was the name used for several classes of midget submarine that the Japanese used in WW2 (including in the attack on Pearl Harbor) - a little machine that packed a punch.
Otherbradbury: My printer. Capable of burning through paper. (Also, this acts as a continuation of the theme that the other SPARC machines started (I named this one last, it ran the factory default hostname for the longest time). What could set paper on fire? A spark. And this has a SPARC.)
None of my Apple devices have interesting hostnames (bhtooefr-ibook for my iBook G4 IIRC (been a LOOOOONG time since I've booted that), bhtooefr-mbpr for my MBP Retina, I don't think the Mac LC has a hostname (I got it to use it as a IIGS peripheral, though, to route LocalTalk traffic), and the IIGS doesn't have a hostname (nowhere to put one, although there is a Unix-like environment for it, but I haven't gotten that running to the point that I can change it from the default).) My phones and tablet run their defaults.
After all of those puns, I think I'll go ahead and put a C-note in the pun jar.
