The machines

Machines at home

When I've got some spare time, I quite like playing with slightly obsolete computers.
mirkwood
Duron 1.2GHz, 512MB RAM, on KR7A-RAID motherboard. Fast network interface, Lots of drives, incl CD-RW. Runs NetBSD -current. Has a 160GB RAID-1 for safe(r) storage using the HPT372 on the motherboard and NetBSD's RAIDframe.
imladris
iBook G3 600MHz, 384MB RAM. Middle-aged version of the 12.1" white iBook. Runs MacOS X (in principle, I planned to put NetBSD on it, too; but actually, OS X is pretty neat). Fairly well travelled.
lorien
Pentium 166 on an elderly motherboard; runs NetBSD 1.6.2 and is our firewall/gateway. Rebuilt after it's K6-2 motherboard blew up a few years ago. It's now got its original motherboard back, but not the K6/166 that went with it; turns out the chip had the infamous K6 bug and it won't play with more than 32MB of RAM.
caradhras
Sparc SLC ('super low cost', no kidding) - a monochrome, diskless, netbooting sparc4-based machine. The NVRAM battery is dead, so you tap in half a dozen OpenBoot lines to get it to start up; but otherwise it makes a great X11 terminal. Runs at 16MHz, if I recall correctly. This machine was a donation from Rob Pearce.
susan
386SX with 4MB RAM, running a seriously manhandled version of Slackware linux. After several years of disuse, susan was revived as a terminal for Tim Cooper to write history papers on. I tried to rename it to fit with the (fairly obvious) naming scheme the other machines use; but it didn't stick.
erelas
Toshiba T1910 laptop - 486 with 8MB RAM. Physically smaller (although heavier) than the iBook, with a 200MB hard drive, and one of the nicest laptop keyboards I've used. Runs NetBSD 1.5, and used mostly as a second terminal on my desk (it's small enough to fit fairly unobtrusively at the back) or occasonally for network diagnostic type things.
greenway
iMac 333; green, strangely enough. Installing NetBSD on it was fun, but we still use MacOS 9 on it some of the time. It sits in our lounge and runs Realplayer for news programmes.
ithilien
eMac 1GHz. It runs OS X 10.3 and is used largely to running ProTools 6.4 for digital multitracking and some MIDI things.

My first machine was an Olivetti M24; I think it's still in a loft somewhere.

Sarah has a blue single-USB iBook, running MacOS 9. It's called bluebottle.

Work machines

I use lots of different systems at work, mostly suns of varying age and power. The machines I care about are:
durandal
Sparc Ultra10 - 450MHz Sparc64 processor, 768MB RAM. Originally used mostly by Andreas for image processing and neural net stuff; I sometimes use it for reconstruction jobs.
anduin
Dual Intel P3-Coppermine/1GHz with 1GB dual-channel RAMBUS. Goes pretty fast really. Runs NetBSD-current with sommerfeld_i386mp_1 branch patches. Used for image processing and reconstruction.
mrweb
Elderly dell P3 450 refitted with a 120G Seagate and a completely gratuitous 512MB of memory to run the MR groups website and resources server. Turns out to be the most solid and stable machine around.
hydra
Cluster: 6 rackmount machines, each with dual P4-Xeon 2GHz and 2GB DDR. It's got some nice SCSI disks, GB ethernet backplane, and is generally rather quick. Still haven't had time to do snazzy MPI things with it and my image reconstruction code yet.
