Tech Fixated reports that the spacecraft's onboard computer system is constrained to 69 KB of memory, a specification set during its design and construction in the 1970s (https://techfixated.com/a-1977-time-capsule-voyager-1-runs-on-69-kb-of-memory-and-an-8-track-tape-recorder-4/). The article identifies the probe as a functional 1977 time capsule still returning scientific readings from interstellar space.

The same source states Voyager 1 records data onto a tape recorder modeled on 8-track audio technology before transmitting to Earth, with the mechanism functioning for over 46 years (https://techfixated.com/a-1977-time-capsule-voyager-1-runs-on-69-kb-of-memory-and-an-8-track-tape-recorder-4/). No additional hardware upgrades have been possible since launch.
