This is an updated note that covers building a working v7 instance from tape files that will run in the OpenSImH emulator. First, the reader is led through the restoration of a pristine v7 instance from tape to disk. Next, the reader is led through adding a regular user and making the system multi-user capable. Then, the reader is shown how to make the system multi-session cable to allow multiple simultaneous sessions. Finally, the system is put to use with hello world, DMR style, and the learn system is enabled.

The note explains each step of the process in detail.
