Let's see I'm running Linux on a Sharp Zaurus, that's not too impressive considering it comes pre-installed (though I'm running a different version than official). I'd install X11 and Apt-get or portage, but I don't know of many apps that would translate to a small screen and usable with the limited processing ability it has.
Specs:
Intel StrongArm 206MHz (sometimes I overclock)
64MB of RAM (32MB used as RAM drive with the current ROM I'm using; TheKompany)
I'm not sure about how much Flash it has
Compact Flash slot (normally filled with a Wifi card)
Secure Digital slot (normally filled with a 1GB storage card, borrowed from my Pocket PC)
Built-in thumb keyboard
I've also run Linux on my Dreamcast using the CD from:
http://www.m17n.org/linux-sh/dreamcast/ Slow and Lacked sound, but it was fun seeing X11 coming up on a TV using a game console. The CVS version of the kernel is supposed to support sound and other devices (such as the VMU flash memory), but no one has got it to compile that I've heard from. The project has been abandoned for some time. The slowness, according to what I read in the mailing-list archives is mostly casued by the fact they had a RAM disk setup so you you could transfer stuff to the Dreamcast using ZModem and a serial cable, and well, the Dreamcast doesn't have very much RAM.
Specs of Dreamcast:
Hitachi SH-4 200MHz main processor
16MB of RAM
Minimal built-in flash (enough to hold settings for using the modem)
ARM based sound processor at like 6MHz (official specs list it at 16MHz, but homebrew developers think it's
alot slower than that)
Yamaha sound chip (connected to above)
PowerVR based video chip
How I had mine setup when I played with it:
Two Dreamcast controllers
An adapter that let me use normal PS/2 keyboards
An adapter that let me use normal PS/2 mice connected to an X10 mouse remote RF receiver (that way I could surf the web from my bed easily), then connected (as the X10 receiver needs a pass-through) to a small touch pad (like you'd have on a laptop)
The hard to find (as it was only sold online, and only two runs in the US) Broadband 100BaseTX ethernet adapter
I have pictures of the above setup if anybody wants it.
Once I get around to modding my X-Box, as it only needs a software hack to work now, I'll probably be running Linux on it. Should make a good Dist-CC box.
an apple ii/gs, though it is an apple ii, its 16 bit and has quite impressive specs. I'm sure people know how apple ii hardware works by now.
I haven't been able to find a Linux for the Apple IIGS, but there is a UNIX version for it that is being given away free now, if I remember right. I don't have a PowerMac laying around, so it's very hard to transfer stuff over the IIGS from my PC (a Power Mac would be able to bridge Ethernet and Apple Talk, not to mention beign able to write the floppy format directly). I have a few IIGSes (and an IIe) laying around to play with if I ever do figure out a way to get stuff onto them. For now, I just play retro Apple II games on them. I have Mac SE that I might put Linux on someday, but I don't mess with it much.
This has gotten me thinking. I think I should around and see what I do have laying around (forgot about the MacSE until this thread) that I might be able to cram Linux on.
