Dean<p>Is emulating an old processor <a href="https://mastodon.social/tags/retro" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retro</span></a> enough? What if it's an old processor doing the emulation? Developing a <a href="https://mastodon.social/tags/Z80" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Z80</span></a> emulator on my <a href="https://mastodon.social/tags/eZ80" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>eZ80</span></a> CPU.

Dean<p>Doing the best I can to distract myself from the madness of the world. Just powered on my latest design for the <a href="https://mastodon.social/tags/eZ80" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>eZ80</span></a> on <a href="https://mastodon.social/tags/RCBus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RCBus</span></a>. A 5V <a href="https://mastodon.social/tags/VGA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>VGA</span></a> graphics module. 640x480 @ 256 glorious <a href="https://mastodon.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> colours. As the guy in the basement would say "it freakin works!"</p>
Dean<p>working on the challenge of implementing <a href="https://mastodon.social/tags/bbcbasic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>bbcbasic</span></a> for the <a href="https://mastodon.social/tags/eZ80" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>eZ80</span></a> with full graphic support (with <a href="https://mastodon.social/tags/V9958" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>V9958</span></a> video). I had forgot just how capable the <a href="https://mastodon.social/tags/bbcbasic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>bbcbasic</span></a> graphics system was. Long way to go - but got the little rocket demo from the original manual working... <a href="https://mastodon.social/tags/RC2014" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RC2014</span></a> <a href="https://mastodon.social/tags/RCBus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RCBus</span></a> <a href="https://mastodon.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a></p>
The Penguin of Evil<p>Achievement unlocked</p><p><a href="https://mastodon.social/tags/Fuzix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Fuzix</span></a> now runs on the classic 6800 CPU using the rcbus-6808 CPU card.</p><p>Took a few small compiler fixes and some other bits and pieces being finished off but with zu2's work on the 6800 code generator all now appears good.
