Lets see..
PPC Machines
- 1x eMac G4 1.25ghz, running Mac OS X 10.4.10
- 1x Performa 6400, running Mac OS 9.1
68k Machines
- 2x Mac SE/30's, running Mac OS 7.x
- 1x Mac IIci, running Mac OS 7.x
- 1x Mac Quadra650, running OS 7.x, and at times, NetBSD
- 1x Mac SE, running Mac OS 6.x
x86 Machines
Servers:
- 1x 1ghz PIII, my primary server, and it runs Debian stable (etch). Its also running a few VMWare VM's, but most of them are Debian etch as well.
- 1x 400mhz AMD K6-2. Runs NetBSD 3.0. Mostly idles, but the plan for it is to be a backup mail server when I start running a server from my house. Hard drive is almost always spinned down.
- 1x 300mhz AOpen MX6E+. Runs the latest IPCop. Don't use it very much at the moment, but if one of the hardware routers fails or something its ready for use. Insanely silent, you'd think its running with passive cooling. Boots from a CF card.
Desktops:
- 1x 1.82ghz P4, running Debian etch. Its more or less my primary desktop now.
I have a bunch of motherboard ranging from 25mhz to roughly 500mhz sitting around collecting dust, but I don't really use them. They'd likely be running Debian for the higher end ones, and NetBSD for the lower-end ones.
