With original Apple ][ ROM it boots to the monitor, most monitor commands work and you can go into Integer BASIC (with E000G or Ctrl-B RETURN) and write and run programs. With an Apple ][+ ROM it boots to Applesoft Basic and runs all the programs I've tried so far.

The only I/O supported is the keyboard and screen but 40-column text, LORES and HIRES graphics are all supported.

ApplePy currently requires Pygame (although there is a minimal that uses curses to display text mode only) and numpy (just for an array for speaker sounds)

pip install numpy
brew install sdl sdl_image sdl_mixer sdl_ttf portmidi hg
pip install hg+
