hkz<p>Given the positive experience with the 386 <a href="https://social.chinwag.org/tags/adapter" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>adapter</span></a>, why not leverage the same process for something slightly different?</p><p>TheByteAttic designed a <a href="https://social.chinwag.org/tags/W65C02" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>W65C02</span></a> -&gt; 6502 adapter that buffers the data bus with an 'HCT245, this is a variant of the same design (with another '245 for inbound control lines too), but, instead of having the transceivers on the side, it uses <a href="https://social.chinwag.org/tags/SMD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SMD</span></a> pins to occupy the exact same space as an original 6502, allowing a <a href="https://social.chinwag.org/tags/QFP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>QFP</span></a> CPU to sit on top of the adapter.</p><p>I'd like to use for repairs on <a href="https://social.chinwag.org/tags/VIC20" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>VIC20</span></a> units.</p><p>So I can do the Shatner.

hkz<p>Last friday I received the shorter pins I bought on aliexpress, to experiment with my <a href="https://social.chinwag.org/tags/QFP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>QFP</span></a> -&gt; <a href="https://social.chinwag.org/tags/PGA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PGA</span></a> <a href="https://social.chinwag.org/tags/adapters" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>adapters</span></a>. <br>I'm quite satisfied how it turned out: easier to insert and extract from a socket, and less vertical space wasted.</p><p>Next step (probably by the end of the month, maybe grouped with other things) is sending the new revision out to print: I optimized a few traces, added pin numbers to the silkscreen and cut the corner for easier PGA orientation. I'll build one, solder another 386 to it, and if it turns out to be stable, I'll release everything.</p>
hkz<p>Woohoo success! Look who's alive!<br>The <a href="https://social.chinwag.org/tags/AM386" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AM386</span></a> i soldered in my <a href="https://social.chinwag.org/tags/QFP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>QFP</span></a> to <a href="https://social.chinwag.org/tags/PGA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PGA</span></a> socket seems fine, and also this <a href="https://social.chinwag.org/tags/repaired" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>repaired</span></a> motherboard is giving good signs of life!</p>
