Borys Pierov<p>While I ended up working on it for about 10 weeks (from few hours once a week to few hours every evening), and probably spending upwards of $100 on materials and components, I'm extremely satisfied with the end result. I knew it will be a long project with lots of challenges, so having all 245 pieces printed, coming together and lightning up felt as quite an accomplishment. <a href="https://mastodon.social/tags/IndicesOfTime" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IndicesOfTime</span></a> <a href="https://mastodon.social/tags/diy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>diy</span></a> <a href="https://mastodon.social/tags/diyprojects" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>diyprojects</span></a> <a href="https://mastodon.social/tags/maker" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>maker</span></a></p>

Today’s unexpected ritalin sidequest… built a shelf out of old bed slats and tidied up the electric / network / junk cupboard in our entrance hall. I would love to pull the whole thing out, organise the trunking and replace the crappy wood on the backing but that would require hiring an electrician for the best part of a day and that just ain’t in the budget right now.

Baby steps in getting my Apple I reproduction PCB up and running. 6502 CPU booting with just RAM and ROM attached. It grabs the reset address from ROM and starts executing code...until it tries to do something with IO, which is not attached yet...

I'm monitoring the bus with an Arduino MEGA attached to my MacBook Pro.
