Where can I watch Old Dora?

Excuse me, could you possibly enlighten me on where one might find the opportunity to view the beloved series "Old Dora"? I've been nostalgically searching for a while now and have had no luck. Is it perhaps streaming on a popular platform like Netflix, Hulu, or Amazon Prime? Or might it be hidden away on a lesser-known service? I'd greatly appreciate any guidance you could offer in my quest to revisit this cherished childhood memory.
