Voyager 1's FDS Lives Again: A Web Emulator
Voyager 1 FDS Computer Emulator
A new web-based emulator brings the Flight Data Subsystem (FDS) of Voyager 1 back to life, letting you run assembly code on the vintage computer that has been flying since 1977. The emulator includes a full instruction set, registers, memory view, and DMA channels, offering a hands-on way to explore the software that helped humanity reach interstellar space.

Are the distance and signal delay numbers supposed to be accurate? NASA's page has them substantially different. Nice work, however!

I was just looking at this yesterday. Apparently Voyager 1 architecture, ISA, etc are well known but Voyager 2 is still denied via FOIA on grounds of copyright.
