transputer internals (was Re: Pentium for Non-PC)

[Ram Meenakshisundaram]

I really shouldn't be doing this, but if you go to http://www.classiccmp.org/transputer/software, you can find tons of goodies including the aforementioned compilers.  ST just really doesn't care about it though...
 
There are some other instruction sets that are out there, but I cant think of them at the moment.  That's strange, but thanks for pointing it out...
 
Cheers,
 
Ram

<groan> I hope there aren't a lot of undocumented instructions. You'd
think the instruction set reference would tell you about the instructions
used by the vendor's own compiler...

When you say C Compiler and OCCAM compiler, do you mean the "SGS-Thomson
Transputer ANSI C Toolset" and "SGS-Thomson Transputer Occam 2.1 Toolset"
you've got product info for on your page? I don't have either of those
(or any others for that matter), could I get a copy from you?

BTW, your mailer seems to add an extra copy of cctalk@ to the To: field
every time you reply.
