This version will only run off of a model 1. (It may run on a model III or IV with a disk CONVERT but I have not tried).

To play you need to create scenarios on tape (tape is needed to save also).

I have tested this extensivly with NEWDOS80 boot (suggest you use this, but should work with TRSDOS or LDOS also). Remember to type BASIC then RUN BUILDER/BAS then build the scenario you want and save it to tape, then type NEW to clear memory, then RUN ORION/BAS and load one of the scenarios you saved from the tape.
