Willard Goosey<p>There's an ebay guy that sells scans of technical manuals. He had the PC4 Sevice Manual. So I got a copy.</p><p>Not a lot to the manual, these things weren't really going to be repairable with 198X equipment.</p><p>This manual also covers the matching cassette interface, though, and I was interested in that. </p><p>Hoped the interface was just some caps and resistors, but nope there's a whole IO chip in there. Outputs Kansas City format tape!</p><p><a href="https://mastodon.sdf.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrocomputing</span></a> <a href="https://mastodon.sdf.org/tags/PocketComputer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PocketComputer</span></a> <a href="https://mastodon.sdf.org/tags/TRS80" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TRS80</span></a></p>
