Ruler is a very early simulation game (The SimCity of 1982).
This version is from 84 according to the program.
In the program the author's name George Greczy is also
mentioned.

I have played it quite a bit, also with friends...

Compared with todays games it is not very impressive and
rather too many numbers. The 41 page manual is a bit much,
but some of the info is useful.

The floppy is bootable and will land you in Radio Shack
Disk Basic v2.2 asking HOW MANY FILES?_ surprising enough.
I think it was meant to start the game automatically but
somehow it doesn't. To get into the basic press {ENTER}
twice. Then type RUN"RULER/JMG and press {ENTER} again.

The disk wasn't protected in any special way and the
RULER/JMG file is a regular basic file and run on any
disk basic I've tried.
