In need of hex files & Instructions for blank display & no sounds on LP II

Hello Moog Forum!

I just purchased a second hand Little Phatty Stage II in great condition but it has the common blank display and no sound output issue. I already purchased the debug adapter but will need the hex files and any other instructions. I repair synthesizers and other electronic music gear on the side and have plenty of experience so I won’t have any issues but would greatly appreciate any help here!

Thank you in advance! :slight_smile:

have u fixed this?
I have the same with the slim phatty
