While originally designed to replace a chip on Ed Brindley's RC2014 YM/AY soundcard it's ideal for other circuits where you use an AY to play ZX Spectrum music.</p><p>The ZXTT provides a clock signal to the soundchip of 1.7734MHz to match the 128K ZX Spectrum ensuring that playback of Speccy tunes is pitch (and envelope!) perfect. (A video on my page shows how much distortion a clock of 1.75MHz gives, which is often used for Speccy related AY circuits.)</p><p><a href="https://mastodonapp.uk/tags/rc2014" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rc2014</span></a> <a href="https://mastodonapp.uk/tags/soundchip" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>soundchip</span></a> <a href="https://mastodonapp.uk/tags/zxspectrum" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>zxspectrum</span></a> <a href="https://mastodonapp.uk/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrocomputing</span></a> <a href="https://mastodonapp.uk/tags/computing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>computing</span></a> <a href="https://mastodonapp.uk/tags/hardware" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hardware</span></a> <a href="https://mastodonapp.uk/tags/electronics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>electronics</span></a> <a href="https://mastodonapp.uk/tags/chiptune" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>chiptune</span></a></p>

RC2014<p>I love how sharp the <a href="https://oldbytes.space/tags/RC2014" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RC2014</span></a> logo has come out. Running a kiss-cut around it after the engrave really helps to darken it up. I think I should have done that with the rest of the lines and text on here too. Shellac has made the cherry veneer look great, but I still want to try wax and oil finishes.</p>

RC2014<p>Thanks everybody that responded, and sorry for not responding to every reply. </p><p>I think the results have confirmed my original thoughts. I will certainly be making a feature of the fact that this computer will run on just 3 chips, so hopefully that will keep the 26% that felt cheated happy.</p><p>As for the 36% Intrigued and 31% Curious, well, you should be. I won't go in to the details just yet, but I'm sure you won't be disappointed.</p><p>There's some updates needed to the prototype, but if all is well, some time next month I will introduce the latest kit to the <a href="https://oldbytes.space/tags/RC2014" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RC2014</span></a> stable.</p>
