Triggered by the discussion and just for fun I went to ROL's homepage... and followed the link to Select. What you get is a page about "Select 4" from 2007. Well that does kind of match the hardware they support But if you start reading since you're into history you do find a discreet link to RISC OS Six. Tricky one...
OK so I followed that link and looked for the end-user features (opposed to the programmer's features) on ROSix site.
First End user feature mentioned is 32/26 bit - followed by a block labelled technical features (things about the kernel ...) and a long module list. As an end-user I'd stop reading just now assuming that if that are the top key end-user features I couldn't care less!
And I assume that quite a few users having a well working RISC OS something (be it 3.x or 4.x) seeing these main ROSix end-user features put their money elswhere - there are quite a few interesting offering for RO available.
But you can even better this since the list (I'm still in the end-user features list) continues with technical stuff mainly .. and when I thought, wow, here comes really something for an end-user all I get is the info like "There is a separate user document covering !Paint in the RISCOS6.Documents directory." That helps.
OK, if the user did not give up yet, the next thing to check is if it will run on his or her system. So off to the FAQ.
The first question, what is RO6, you see a list of computers and the note "Complete support for some of these computers may require additional software development which has not yet been undertaken." That helps since they prefer to not even tell you which ones are completely supported!
Then in the next block about the comptuers RO6 will be available for you can read "The full Select 4 Issue 4 release is a softload suitable for Risc PC, A7000 and Virtual Acorn products".
Yes, they tell you about comptuers running Select 4 and further down that RO6 is something different...
Only for one piece of hardware you get a definitive information: IYONIX pc! It does not run on that one. And for a few like Omega, Mico and R7500 you can read that they will not be officially supported.
So for Risc PC, A7000, VirtualPRC, A9home, to name the main ones, you can just hope/guess/assume
IMHO, if ROL really wants to sell ROSix they should think about trying to convince the users of older RO versions and assume that quite a few of those are just users - not programmers or users not knowing where to put their money!
Lucky me with an IYONIX pc since when friends ask me about what RO is I can always point them to ROOL's site...
