I&amp;#x27;m the author of the project and I&amp;#x27;ve seen it pop up here on HN a few times when searching but I haven&amp;#x27;t seen it make it the front page until now.&lt;p&gt;It&amp;#x27;s been really fun pushing the limits of the RP2040 microcontroller and learning how to use its PIO capabilities has been eye opening. I&amp;#x27;ve created PIO code to handle the ISA bus and interface with SPI-based PSRAM at higher speed than I could with the RP2040&amp;#x27;s built-in SPI peripheral.</text></comment>
