Hello All,

Guys I'm completely new in this OS, in my work people start a project to internalize the Unisys MCP systems and is completely different from everything I ever tryed haha.

As doesn't have MCP Express anymore I trying to find anything I can run and trainning to understanding better the OS.

I'm trying to build from source the system but I froze in some parte that I can't understand. The erro is about some file that is read-only but I can't find it. Anyone knows how to sove it. I really apreciate your help.

I'm sorry, but I cannot help you with problems related to the SIMH emulator for the B5500. The retro-b5500 emulator is written in JavaScript and runs in a standard web browser. For the SIMH-based emulator, I suggest you contact Richard Cornwell at @.***

That said, I think you're wasting your time trying to learn about the modern Unisys MCP from a B5500 emulator and operating system. The B5500 was a system used in the 1960s and early 1970s, and the versions of that MCP operating system available to us are more than 50 years old. The B5500 was a forerunner of the modern Unisys MCP systems, and there are some similarities in the architecture, but nothing you learn about the B5500 will be useful for the modern MCP.
