Hello everyone!
20 years ago I sold my old Big Muf Pi and now I am very sorry. I want to order such a he on ebay, but I don’t know if it’s 4 or 5. I still have a drawing of the scheme, it may not be accurate, but the main thing for me is to find out if there is a buy pass on the scheme or not, If not, then this is m 4 help me figure out who is in the know, sorry for AI English.
