I realize the Voyager project may not be super well funded today (how is it funded, just general NASA funds now?), just wondering what they have hardware-wise (or ever had). Certainly the Voyager system had to have precursors (versions)?

Or do they have a simulator of it today - we’re talking about early 70’s hardware, should be fairly straightforward to replicate in software? Perhaps some independent geeks have done this for fun? (I’ve read of some old hardware such as 8088 being replicated in software because some geeks just like doing things like that).

I have no idea how NASA functions with old projects like this, and I’m surely not saying I have better ideas - they’ve probably thought of a million more ways to validate what they’re doing.
