Enthusiast ‘lands’ on the moon using hardware from the 1980s — ZX Spectrum home computer with 3.5 MHz CPU and 48KB of memory power Kerbal space flight

Space enthusiast and YouTuber Scott Manley used a ZX Spectrum, a home computer from the 1980s, to successfully "land" on the moon in the Kerbal Space Program simulator. The ZX Spectrum, with a 3.5 MHz CPU and 48KB of memory, controlled the virtual spacecraft in the simulation. Despite its limitations compared to modern computers, the ZX Spectrum's capabilities were highlighted in this feat. Manley had to creatively program the device to operate the virtual spacecraft and connect it to the simulator using a proprietary storage system with an RS232 Serial port. This achievement showcases the ingenuity of past engineers who landed on the moon with less powerful computers than what we have today.
