If you want to keep it super cheap, try to find a Linux user upgrading to
the 512MB version. 256MB is a vast amount of RAM for Risc OS, whereas it is
not enough for a graphical Linux desktop. You really don't need half a gig
for Risc OS, unless of course you want to run Linux as well.

Well, a modern one, anyway. I remember running KDE quite happily

and that's without graphics. I'd like an OS that's compatible
with the modern world but which lets me put old/small machines to
serious use, a la Classilla.
I guess the Open Source credo would tell me to suck it up and

All "B" models have Ethernet; The "A" model will not have it.

Raspbian is a debian flavor for Pi. The 'bloat' would be when you
want to run Java apps under X...

There is a connector for a serial port. It's 3.3V levels (like all
the other I/O pins), so you need suitable line drivers. It will even
work as a serial console if you so desire. You can use one of the
3.3V FTDI cables or roll your own circuit with discrete components or
a Dallas-Maxim chip.

I keep (some of my) my electronic notes on it, use it for developing
handy ruby scripts and keep a simple webserver running on it. I'm using
git and periodically pushing to a NAS box. It's a DNS server for the
home network. It will eventually be a NIS server too (so I can set up an
environment like the one at work with "single sign on"). If I go ahead
and get a second one to use as a media treamer for the TV, I'll probably
use this one (256MiB) for the media and the new one (512MiB) as the
household workhorse.

I've got as far as installing SIMH on mine. I've not yet grabbed a VMS

Too many projects, too little time ...

Looking at the info on the Raspberry Pi website, it looks like the
CPU is equivalent to about a Pentium II 300Mhz. That would give it
about 1.5x the speed of a KL10 under KLH10, or maybe 2x a fast PDP-11
under E11 or SIMH, I suspect it would still be slower than a
VAX-11/725, VAX-11/730, or MicroVAX I. I think an Atom board would
be the minimum for VAX emulation.

If
you do keep these sorts of services on the device, recall that SD
failure modes tend to be horrible and unrecoverable. they simply
brick. Hopefully you can periodically back it up, or spend the extra to
have a duplicate for when that might happen.
I'm running 64gb in both of mine and they run quite well. I'm not
hosting any data on them however that I can't replace by duplicating the
other PI's chip.
I'm actually thinking about shifting to the Odroid 1.7ghz Exynos 4412,
both because it will run android and because it is in my phone (Galaxy
Note II). I want both Linux for my development and some media usage,
whith XBMC and with the Android Jelly bean for other media uses in the
house and elsewhere.
I am hosting some emulators on the PI, but will probably move them to
the odroid if it proves to be fast enough. Object is to reduce the
house intel server population to just one vmesxi system.
thanks

Yes, that would be my thought, too. I don't
particularly care about the
extra RAM, but having Ethernet is a must (for me). Actually,
While only yhr Model B Rpi has on-board ethernet, I am pretty sure it's a
USB to tthernet device hung off a USB port on the SoaC. I am also prtty
sure you can sue a USB ethernet thingy with a mdoel A if you want to
I can't remember now; does the 'Pi have RS232
built in (poss. with the

To be pedantic, no. TO be practical, yes.
There is an asynchronosu serial port on 2 pins of the GPIO connecotr.
It's not RS232, it's 3.3V logic levels. But you can easily buffer it
(MAX3232 IC) to RS232 levels. The Rpi can use that as a serial console
too. By default it runs at 15200 baud (something which is very PC
speciifc, nd a ridiculous choice fothe default), but you cna set it to
just about any seped in one of the oconfiguration files.

New subject: OT: Linux-to-OpenBSD device drivers
This is way off-topic, but maybe someone has run into this problem.
I have a server here running OpenBSD (x86 32-bit) and I don't want to
change the OS, but I would like to add a Linksys USB-to-Ethernet adapter
(2f09). Said adapter comes with the source to a Linux driver, but I've
never worked at the driver level in OpenBSD.
Does anyone know how difficult it would be to modify/recompile the Linux
source to work in OpenBSD?
Thanks,
Chuck

They're quite different, though having the driver as a guide to how
to use the hardware is handy in the absence of a datasheet. Are
you sure there's not already a driver? I don't see "2f09" as a
Linksys product, but this would suggest that there is at least
partially-working support for the 300M, which seems to be their
currently-available adaptor:
http://comments.gmane.org/gmane.os.openbsd.tech/21147
Most commercial USB->[Ethernet|WiFi] adaptors use one of a small
handful of common chips, and OpenBSD is generally fairly good about
driver support for them. You may find that the driver you seek is
already available, though you may need to update to a newer OpenBSD
version to find it.
tl;dr It's not an easy drop-in to run a Linux driver from source on
OpenBSD. Better to find an existing one.

Here's what lsusb gives me (extraneous endpoint information elided):

I can find nothing on the web about this thing other than a couple of
mentions about not being able to find drivers. If necessary, I can
crack the thing open and see what's on the PCB.

I'll see what I can do--a little messing around and the thing seems to
be known as a "HG20f9". XP found a driver for it right away--and it
appears that the Debian people have heard of it as well (there's a
driver on Github).
I'll look through some of the OpenBSD drivers and see if I can find
something close to hack up.
