Sorry to revive this dead thread, but google led me here when researching… Does anyone happen to have a service manual for the PT-100 or any of its close variants? MT-56 or MT-105 perhaps? I’ve been looking for ages and have turned up nothing :/ By the way, it’s an honor to post in the same thread as you, Windler. I’ve been using your site for years, it’s an incredible resource for circuit bending & vintage keyboards, i’ve referenced it during my builds too many times to count
