Stair Runner

The keyboard graphic responds to mouse clicks, touch events, and key presses. Hold your shift key while clicking the PET keyboard to get the graphics characters. (The emulator simulates pressing the PET's left shift-key at the same time as the clicked key.)

Changing the size of memory or changing the ROM version forces a reset of the PET.

The emulator has an IEEE-488 device at address 8. It can be used load and save (.prg) files.

Some programs don't run on ROM1 and some require more memory than the default 8K.
