If no filename is given, the emulator will ask for it. OMF binaries carry entry point information so the machine will start running at the correct spot, but raw binaries do not. For raw binaries the machine starts with CS=IP=0.
Keys Inside the emulator:
R Run/Stop the Emulator
S Single step the emulator
F Clear machine fault
1-5 Levers
F1-F5 Buttons
Keypad Controls the machine's Keypad
Z,X,C Forces a timer0, timer1, timer2 interrupt
That's about it.
