I don't think there is a dedicated archive feed for Show HNs, but as a workaround you can use the search to get a list of older entries: <a href="https://hn.algolia.com/?query=Show%20HN:&sort=byDate&prefix&page=0&dateRange=all&type=story" rel="nofollow">https://hn.algolia.com/?query=Show%20HN:&sort=byDate&prefix&...</a>
