Helios

HeliOS was a Unix-like operating system for parallel computers developed and sold by Perihelion Software. It was most commonly used on various Transputer systems, but also supported other architectures. The system provided a micro-kernel that implemented a distributed name space and messaging protocol, through which services were accessed. A POSIX compatibility library enabled the use of Unix application software, and the system provided most of the usual Unix utilities.

The ATW800 was first introduced, under the name ABAQ, at the COMDEX show in Las Vegas in November 1987. Depending on which version of Atari's documentation you read, either 50 prototypes were released in May 1988, and 300 production machines in May 1989, or else there were 100 prototypes and 250 production machines. In either case it would appear that 350 machines were built in all. In 1995 ACN in the Netherlands held what appears to have been the final “closing-down sale”, and of course Atari no longer exists as a company: so ATWs are now only obtainable second-hand.

Software

In the mid/late 90ies I maintained an FTP server (ftp://wuff.mayn.de - later ftp://ftp.mayn.de) and a part of it focused on Helios. The FTP server is probably long shut down by now (I am no longer a member of the association that ran it) so I thought its a good idea to provide these binaries here:

Helios 1.2

Helios 1.3
