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.
In PICKUP, you move around a cluttered screen picking up matching PETSCII symbols and returning them to one of the goal squares in the corners. Control with the numeric keypad is tricky but according to the flyer, control with the joystick (optional) is even trickier. You can control the speed and time limit for the game. Blitz mode (maximum speed, one minute time limit) is a real challenge. Be prepared to embrace imperfection.
