Controls
Boots the Xerox Alto from a disk pack to the Alto Executive on the tall 606x808 bitmap display. Click the screen to give it the mouse and keyboard (the Alto is a GUI machine, so the pointer drives the Alto mouse). Type "?" and Return at the ">" prompt to list the disk. Open the debugger to single-step ONE emulated Nova instruction, watch AC0-AC3 / PC / L / cursor change, set breakpoints on the program counter, read core memory in octal, and set write watchpoints. Boot may take a few seconds while the disk pack downloads.
