Quazar<p>Another demo of my new SAA1099P Soundchip Interface for RC2014 &amp; Compatibles.</p><p>I've quickly knocked together some code into a ROM chip to play E-Tracker music via the SAA1099P soundchip interface. (E-Tracker is chiptune tracker software for the SAM Coupe.) </p><p>Hardware in use...</p><p>* SAA1099P Soundchip Interface <br>For all the information on this please see my website with all my RC peripherals and expansions at:<br><a href="https://2014.samcoupe.com" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">2014.samcoupe.com</span><span class="invisible"></span></a><br>(I've also got the interface listed on Tindie and eBay.)</p><p>* SID Soundchip Interface<br>- My first peripheral for the RC2014 from June 2020, but of course here the SID isn't being used. What is being used is the interrupt controller on the card to generate 50 interrupts a second for accurate triggering of the music playback routine. (It can generate 50/60/100Hz interrupts - ideal for lots of chiptune uses!)</p><p>* RC2014 Mini v1.1 with my custom ROM.</p><p>* SC112 Backplane</p><p><a href="https://mastodonapp.uk/tags/Quazar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Quazar</span></a> <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/SAMCoupe" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SAMCoupe</span></a> <a href="https://mastodonapp.uk/tags/chiptune" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>chiptune</span></a> <a href="https://mastodonapp.uk/tags/synth" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>synth</span></a> <a href="https://mastodonapp.uk/tags/demoscene" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>demoscene</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/Z80" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Z80</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/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrocomputing</span></a></p>
RC2014<p>I feel bad that there haven't been any <a href="https://oldbytes.space/tags/RC2014" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RC2014</span></a> updates recently, despite the fact that there's a lot going on.<br>A lot of things seems to be depending on everything else, leading to an all-or-nothing workload. I think there is going to be a flurry of new releases towards the end of the month (or early September) though. </p><p>In the meantime, if you can make it to <a href="https://oldbytes.space/tags/RC2014Assembly" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RC2014Assembly</span></a> at Bletchley Park on September 20th, <a href="https://rc2014.co.uk/3855/rc2014-assembly-v1-0/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">rc2014.co.uk/3855/rc2014-assem</span><span class="invisible">bly-v1-0/</span></a> it would be great if you can sign up - particularly if you have something interesting to display or show off.</p>

This looks like it is going to be an awesome day with people showing off their hardware, demonstrating their software, and talking about what interests them with the RC2014 (including similar platforms like the RCBus or Z50 bus machines, or kits that run RomWBW etc).</p><p>Tickets don't go on sale until tomorrow, and I will post a working link (sorry about the oopsie in the newsletter) when they're available.</p><p>I hope that as many of you as possible can make it along, especially if you don't normally attend general retro computer meetups.</p>

And you can buy it as a completely unassembled kit, which I did. So I'll be breaking out the soldering iron!</p><p>2/</p>
