Voyager's computer systems were custom-built using 1960s technology, with clock speeds measured in KHz and RAM in kbytes, running hand-crafted software, crammed into 4K of 18-bit wide plated-wire memory (similar to but better than core mem).
And yes, it uses digital 8-track tape for storage.
The custom-designed hardware, (upgraded) software and instruments are mostly still functioning after 46 years in space!
