Minicomputer Part 5: Building an Arduino ROM Reader

In this episode we take our first step towards ensuring that we have a backup plan if all the magic smoke comes out on first power up – we rip the data off the ROMs! It’s not as easy as it sounds though as these ROMs are pretty old and weird chips that aren’t supported by a lot of ROM programmers out there, so in the end, we end up building our own ROM reader from scratch using an Arduino and some 74LS161s!
