<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.
