I don't know if this will help you, but a guy in Sweden made a PDP-8/I out
of a Raspberry Pi which he calls a PiDP-8/I with a custom made authentic
looking slightly smaller version of the PDP-8/I front panel. The following
url describes the OS-8 he used on simh running on a version of linux on the
Maybe the OS-8 information on that site might help you. I don't think I
have ever heard of MultOS-8, but I'd like to be kept in the loop on your
project and learn more about it. I haven't bought my Pi 3 yet, but I'm
planning on getting it soon to finish my PiDP-8/I Kit and get it
operational. I pray you can find everything you need and get logged into
your MultOS-8 installation. Take care my friend.
