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.
Would they be different? They launched 16 days apart. I always assumed they were mostly the same core hardware. hm... rereading the wikipedia pages now...
This was common back then. The PDP-8 had eight primary instructions, although one of them was multi-purpose. This helped keep the hardware simple when we didn't have ICs.
RISC isn't about having a small ISA but about a regular, orthogonal instruction set.

The author has also published a Setun-70 emulator (a Soviet ternary computer rather than a binary one):

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

Next add realistic signal delay so you have to wait a day to get the result
Is it possible to hook this up to some kind of satellite space simulator to control a virtual voyager?
it would be amazing to include a few example programs!
Click the "Load Example" drop-down menu in the bottom-right corner.
Wow. Only 10 instruction set? Looks like father of RISC cpu design

- stupid question: what is the program about? what are we trying to achieve?
It emulates the computer that runs Voyager 1.
I'm not sure I understand the question.
