Charlie Balogh<p>Yes, I know, I could have 3D printed something, but I really lack the space for a 3D printer, and I have too many tools I barely use anyway. Plus I don't have experience in designing these kind of things - although would be very interested, but not having a printer is kinda demotivating. This was just way faster and simpler - for now.</p><p>On a related note and looking sharp - used the white-on-black labels to add some other matching labels here and there.</p><p><a href="https://mastodon.social/tags/x68000" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x68000</span></a> <a href="https://mastodon.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> <a href="https://mastodon.social/tags/m68k" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>m68k</span></a></p>
Charlie Balogh<p>Still wrapping up some small projects after the holidays. This time, I put the X68000 USB mouse adapter I built previously into a case.</p><p>The small plastic box I bought for this is slightly too big, but I padded it with some foam I had at hand. Proper zip-tie engineering results in good enough stress reliefs. Add some white-on-black labels to make it look... SHARP. (Sorry...)</p><p>Not too bad for a first try and it still works - the Arduino survived the surgery.</p><p><a href="https://mastodon.social/tags/x68000" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x68000</span></a> <a href="https://mastodon.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> <a href="https://mastodon.social/tags/m68k" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>m68k</span></a></p>

Charlie Balogh<p>If you ever wanted to know, yes, an Amiga 4000T and a CyberStormPPC (or MK3) boots into working AmigaDOS Shell with 2MB chip RAM only. </p><p>Why?
