So, I've got my Upduino boards the other day and found out that the available docs are spread throughout the internet, the code examples don't work or are missing build instructions, and the official manufacturer-supplied tools require multiple hard to remember and follow steps. I figured there's got to be a better way, so I'm describing it here.

So you've got your Upduino. What now?

Upduino is a dream come true for my 8-years-ago self - a cheap FPGA capable of holding nontrivial CPU designs that you can program in an easy way. Like an Arduino. Get it? Upduino. Arduino. Almost as if it were on purpose.

Cranking out another post took me way longer than I had anticipated when I rebooted this blog, but I got sidetracked by another quick hardware project that turned out to be way more involved and equally more fun than I originally thought...

I've designed an Atari 400/800/XL/XE standard cartridge compatible board that can hold up to 127 different standard 8KB and 16KB game ROMs at the same time. It's memory chip agnostic and features software game selection & a few neat hacks.
