Thanks to kits like <a href="https://oldbytes.space/tags/Z80mbc2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Z80mbc2</span></a> or <a href="https://oldbytes.space/tags/rc2014" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rc2014</span></a></p><p>But since it's from the 1970s and still almost forgotten by or unknown to most people, it's almost logical no-one ever put up such a video. </p><p>As you have witnessed, most peope are happy to just run "Zork" and then move on, not being interested in learning assembler or anything about that very cool OS and the CPUs that powered it back in the day.</p><p>So it would be very interesting to see some deep-dive video documentation sometime. Sounds like a fun project!</p>

Paolo Amoroso<p>I tested the Beagle Term terminal emulator with the Z80-MBC2 and V20-MBC homebrew Z80 and Nec V20 computers.

Paolo Amoroso<p>The two homebrew CP/M computers I use and love have logos that give them personality.</p><p>The Z80-MBC2 Limited Edition features a &quot;Z80 inside&quot; logo similar to the iconic Intel branding. The logo of the V20-MBC Black Edition, a two-flavor ice cream cone, is a nod to its Nec V20 chip with the 8080/8088 dual mode.</p><p><a href="https://fosstodon.org/tags/z80mbc2" class="mention hashtag" rel="tag">#<span>z80mbc2</span></a> <a href="https://fosstodon.org/tags/v20mbc" class="mention hashtag" rel="tag">#<span>v20mbc</span></a> <a href="https://fosstodon.org/tags/retrocomputing" class="mention hashtag" rel="tag">#<span>retrocomputing</span></a></p>
Paolo Amoroso<p>The boot menu of the Z80-MBC2 homebrew Z80 computer has an option, &quot;autoboot&quot;, to load and execute a designated file on the device&#39;s microSD card. The option runs this tool, which looks like a raw disk editor.</p><p><a href="https://fosstodon.org/tags/z80mbc2" class="mention hashtag" rel="tag">#<span>z80mbc2</span></a></p>
Paolo Amoroso<p>You have a working homebrew computer, now what?</p><p>Some enjoy the challenge of designing or making a computer kit. I have no hardware assembly skills, so I start from there by learning the operating systems of these devices, exploring software, and coding. I publish ongoing series of blog posts about my retrocomputing projects with these CP/M homebrew computers:</p><p>Z80-MBC2 (Z80)<br /><a href="https://journal.paoloamoroso.com/tag:z80mbc2" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="ellipsis">journal.paoloamoroso.com/tag:z</span><span class="invisible">80mbc2</span></a></p><p>V20-MBC (Nec V20)<br /><a href="https://journal.paoloamoroso.com/tag:v20mbc" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="ellipsis">journal.paoloamoroso.com/tag:v</span><span class="invisible">20mbc</span></a></p><p><a href="https://fosstodon.org/tags/retrocomputing" class="mention hashtag" rel="tag">#<span>retrocomputing</span></a> <a href="https://fosstodon.org/tags/projects" class="mention hashtag" rel="tag">#<span>projects</span></a> <a href="https://fosstodon.org/tags/z80mbc2" class="mention hashtag" rel="tag">#<span>z80mbc2</span></a> <a href="https://fosstodon.org/tags/v20mbc" class="mention hashtag" rel="tag">#<span>v20mbc</span></a></p>

Paolo Amoroso<p>Prior to the V20-MBC I got a Z80-MBC2, another homebrew computer by the same maker and with a similar design but with a Z80 CPU instead of a Nec V20. The photos show the device, alone and plugged into my Chromebox.</p><p>I&#39;ve been having a lot of fun with the Z80-MBC2, which runs CP/M and other retro operating systems.
