    Pac Man uses a slow 3 Mhz Z80 8 bit CPU while the PDP 11 is a real 16 Bit computer. Give it some kind of video memory, and it wouldn't have any problems handling Pac Man.

  • @6364gg2 There was even a primitive Pacman for the 'Hewlet Packard HP48' pocket calculator programmed in Chip8. That thing had an awfully slow 32KHz CPU and still could handle it.

  • He did it as a joke...

  • For a second I thought it was the text-terminal Pacman port I made for RSTS/E on VT52 terminals. I lost the source but I'm seriously considering recreating it under an emulator

  • Maybe Pacman, but Ms. Pacman requires a PCI-e video card for decent FPS. Unless you got one of the newer smoking hot Atari 2600 consoles.

  • What happens when you get to screen 256??

  • i can run gta4 on one of that too... lol XP

  • Actually it probably could play pacman if it had a graphics card or refresh vector or raster graphics terminal.

    I believe this model was pretty close to the same performance as a 4.77MHz PCXT executing around 380,000 instructions per second.

  • Just add the FPU option ;-)
