 - The second line loads the BASIC5 image at $1100 (0100H for the Z80).
 - Finally we just run the 6502 code in `SOFTCARD65` to bootstrap the process.

 The other EXEC file `RUNTESTSTUB` is the same, but omits the second step.
 Instead of running BASIC, it runs some internal test code that is part of
