Question, how does it compare to Unix? It seems to be a mainframe OS.
- pjmlp 7y agoFirst OS written in a high level programming language, without any kind of Assembly, back in 1961. The systems language was an Algol derivative named ESPOL, later replaced by NEWP a bit more powerful. Instead of requiring external Assembly support, ESPOL/NEWP have compiler intrisics for hardware access. One of the NEWP improvements was the introduction of UNSAFE code blocks, any binary with unsafe code is tainted and requires being greelighted by the administration for execution. It was originally known as Burroughs B5000, https://en.wikipedia.org/wiki/Burroughs_large_systems https://en.wikipedia.org/wiki/Burroughs_large_systems. Naturally Unisys uses the security and data integrity theme as the target segment for getting a ClearPath MCP toy. https://www.unisys.com/offerings/clearpath-forward/clearpath-forward-products/clearpath-mcp-software https://www.unisys.com/offerings/clearpath-forward/clearpath... https://www.youtube.com/watch?v=xatHCXEkOsY&list=PLzXIyqnmO3G-NP-E1Zfa7KmVQLoQDLQ6I https://www.youtube.com/watch?v=xatHCXEkOsY&list=PLzXIyqnmO3... There are also Visual Studio plugins for developing remotely with ClearPath, https://www.youtube.com/watch?v=IHLx1Bc4lH0 https://www.youtube.com/watch?v=IHLx1Bc4lH0 A recent version of NEWP reference manual can be found at https://public.support.unisys.com/aseries/docs/clearpath-mcp-17.0/pdf/86002003-407.pdf https://public.support.unisys.com/aseries/docs/clearpath-mcp...
