Have you ever found yourself in the need of a nine channel scope, when all you had was an FPGA evaluation board? Do not despair, [Miguel Angel] has you covered. While trying to make sense of the inner workings of a RAM controller core, he realized that he needed to capture a lot of signals in parallel and whipped up this 9-channel digital oscilloscope.
Oscilloscopes occupy a special place in hacker lore, be they analog home-made ones, units used to play Quake, or being tricked into working outside their specifications. The last one even features comments that recommend the use of an FPGA similar to the one used here.
