Yay, Tim! Did you ever find a version of portaudio[1] for RISC OS? Much more pleasant as the basis of audio and MIDI primitives, as it provides a sane C API to multiple host platforms' media APIs.

Equally important, how many of us on the list remember how to ask Squeak to play a Bach fugue on *any* VM?

I could never forget [AbstractSound stereoBachFugue play], just like I'll never forget [WarpBlt test3]. :)

There is now a RISC OS Squeak 4.0 with actual sound output available for testing - try http://www.rowledge.org/tim/squeak/Squeak3-9c-RISCOS.zip to download a bundle of the entire squeak setup, including the DeepKeys and SharedSoundBuffer modules, the Squeak .source file already installed and the image/changes file ready to go.

And if that seems to work, you might try a very sketchy Scratch try-out by downloading http://www.rowledge.org/tim/squeak/Scratch-RISCOS.zip – but you’ll need to have grabbed theSqueak package first in order to have the deepkeys/ssb modules.

Neat! In case I wanted to try this, I would download RISC OS from

http://www.raspberrypi.org/downloads

and make an SD card with the disk image. Boot the RPi with it, and then ... what?

Very cool indeed. I've never actually had the chance to try a RiscOS machine, and it looks like this Raspberry Pi gadget would be a good low cost way to try it out. I figure any gadget that can run Squeak can't be all bad :)

Ok, this is interesting because it's very like trying to explain to a newcomer how to get started with Squeak. There is no Big Corporation with a Publications Department that we can turn to; it's all volunteer work and very spotty.

For hardware you need the typical RasberryPi bits; a monitor that can be driven by an hdmi port - so hdmi & DVI is easy, VGA is a bit more expensive to get an adaptor cable for. I got an hdmi->DVI cable for $3 from ebay. a power supply; a micro-usb cellphone wallwart is typical and available on ebay for $2-5. a usb keyboard & mouse. You probably have these acting as doorstops or bookrack levellers. ethernet *cable* - RISC OS does not currently do WiFi. SD card - 2Gb, 4Gb is ok but half will be wasted, fastest you can find. As for cases, read the Pi site forums for about eleventy-billion cases hacks. I stuck mine in an old miniMac expansion box from newertechnology.

I'd start by looking at the RISC OS Open Ltd site (www.riscosopen.org) and hitting the 'Documents tab. There is a tolerable and slowly growing collection of explanation pages that should help. Feedback from the totally new user would be helpful just as with Squeak doc. Definitely start with the Raspberry Pi install guide (https://www.riscosopen.org/wiki/documentation/show/Beginners%20FAQ:Installin...) and get the SD card image from (http://www.raspberrypi.org/downloads) first so you can get it downloading while you read https://www.riscosopen.org/wiki/documentation/show/Introduction%20to%20RISC%... as a basic intro. Warning - RISC OS will seem *weird*. Not to mention *retro*.

A good read for a quick idea of what you're getting into is https://docs.google.com/viewer?a=v&pid=sites&srcid=ZGVmYXVsdGRvbWFpb... and maybe http://www.svrsig.org/Beta.htm

Once you have recovered from the culture shock, got it on the net and worked out how to fire up NetSurf, head for my website and download away - www.rowledge.org/tim/squeak/Squeak3-9c-RISCOS.zip and just unzip it by double-clicking on the zip file and dragging the contents to the filer window of your choice. Read the Important File That Must Be Read inside the 'deepkeys' and sharedsoundbuffer' directories. Then just d-click on the image file and away you go.

Note that this is Squeak 4.0 you're getting for now. Later versions, well, later. Cog sometime soon if somebody can find a way to keep me from going broke whilst doing it.

For Scratch, also download the http://www.rowledge.org/tim/squeak/Scratch-RISCOS.zip and unzip etc - you can get assorted projects and media files from the Scratch site. Let them pay for bandwidth! Scratch, I would point out, is built on a 2.8 image, so it's … primitive... for system support.
