The Penguin of Evil<p>Need more CPU power, your <a href="https://mastodon.social/tags/rc2014" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rc2014</span></a> mini-cray not pulling its weight, jealous of people with multiple CPU cores. All that can be in the past. The new ECP180 allows you to put up to 8 Z180 processors to work at once on your system (16 with a small PCB mod). Each unit as a shared memory interface and 512K of local SRAM as well as local serial and SPI/SD interfaces via the CSIO in case you want to build a classic MP/M &amp; CP/M multiuser box S100 style</p><p>Hardware release very soon</p><p><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>Managed to route the <a href="https://mastodon.social/tags/rcbus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rcbus</span></a> Zilog Super8 card today and the 80C196KB CPU card. Some compromises needed on the 801C96 in particular to get all the I/O on the card. Both a bit bigger than standard <a href="https://mastodon.social/tags/rc2014" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rc2014</span></a> size but who cares. In fact it may even be helpful as some of the connectors are quite tall (PS/2 especially).</p><p>The super8 also hopefully has 8bit DMA driven digital audio because one of the 8bit ports can be driven via DMA and an external ack, and there is a timer output pin</p><p><a href="https://mastodon.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a></p>
