[Simh] tty magic(?) for talking to bootloaders?

[Richard Cornwell]

Hi,

   You might want to check out what I have done for the B5500 and
   PDP10. 

   http://sky-visions.com/burroughs/xiii/

   Are the files that will rebuild MCP XIII from source, including
   build jobs.

   The install and load TOPS 10 5.03 or 6.03 you can find the simH init
   files here:

    http://sky-visions.com/dec/tops10.shtml 

        http://sky-visions.com/dec/tops503/

        http://sky-visions.com/dec/tops603/

    These scripts use simH expect send to drive the simulators.
