To play Michael Gardi’s PDP-1 Lunar Lander in a browser, download lunar_lander.rim from the project page, open it in the JS-PDP-1 emulator, and click READ IN. Use J or A to rotate clockwise, L or D to rotate counter-clockwise, and hold S or K to thrust.
Load the game in JS-PDP-1
- Open the Lunar Lander for the PDP-1 project page and locate
lunar_lander.rimin its Files section. Download the file. - Open the JS-PDP-1 emulator and use its file chooser to select the downloaded RIM file.
- Click READ IN. The project author says this loads and starts the game.
- When the NEW GAME screen appears, press one of the control keys to begin.
Steer and land
- Rotate clockwise: tap J or A.
- Rotate counter-clockwise: tap L or D.
- Thrust: hold S or K.
Try to land at the six sites described by the author while conserving fuel. The author says landing at all six earns a 1,000-point bonus. The stated “Good Landing” criterion is H<50,V<100; the project instructions do not specify the units for H or V.

Which Lunar Lander is this?
This is Michael Gardi’s graphical PDP-1 game project, not the earlier text-based Lunar Landing Game associated with the PDP-8. The documented browser workflow needs the game file and emulator; it does not require a physical PDP-1 or a PiDP-1 replica.

If the steps do not match your screen
The project instructions do not specify a JS-PDP-1 version, minimum browser requirements, or a verified troubleshooting procedure. If lunar_lander.rim is missing or the emulator labels have changed, check the project’s current instructions rather than assuming a particular workaround.
