Oh man, if only I knew what was wrong with it half the time. I've replaced the ROM with 1.9 since it supposedly has diagnostics but they don't tell me much. I've been trying to design a new cartridge for it, but writing to it is always super funky. The service manual doesn't exactly say what the timings are supposed to be, just the pinout.

Mostly though I've just got some weird dirty hiss (sounds like a rainstorm) on the output all the time that makes it unsuitable for recording. I use DEXED + midi in that case, but it's still fun on it's own (also weirdly I find menu-diving to edit patches easier than being presented with that big DEXED UI)

Thanks for keeping these things alive
