There is a Helios ISERVER at INMOS. The modification required a new
linkio module. ISERVER, and the INMOS tools (native not hosted) work fine
under Helios. You will need to create two domains in your Helios network,
one to run Helios, the other "native". Run the ISERVER on a transputer in
the Helios domain adjacent to the "native" domain. It should have the
reset/analyse subsystem driver installed. The Helios domain will then emulate
a "host" in the normal ISERVER sense, and boot the other transputers as
usual. A neat optimisation is to install the binaries of the INMOS tools in
a ramdisk, and your own .BTLs too, then the ISERVER will load your code right
out of RAM. Imagine, the OCCAM compilation system, itself hosted by a CSP
multiprocessor machine with an X windows UNIX environment, magic!

(BTW, a while back there was a discussion about the merits of INMOS' hosted
vs. native transputer tools policy. IMHO, this is yet another good reason to
continue support of the native tools). 

The source is supposed to be in the public domain, and it should be on the
ftp site at INMOS somewhere. But since I'm no longer there I can't e-mail it 
to you. Maybe someone else could (~raw/helios...). Also, Rob Kurver at PACT
has a copy, and they ship it with their C compilation system. 

You should be able to get a copy somewhere,
 
Rob / Perihelion, INMOS folks listening ?? are you able to help this guy.
 
Cheers,
