GSP 2101 Artist quit working
Hey guys. I have an old GSP 2101 Artist from the mid 90’s that has worked flawlessly since I bought it. I went to change the preset I was using with the dial and it threw up an error code. I changed the battery in it and now there is a different screen. Says “I need a PPC.” Just wondering if anyone had run into this before and also how to swap it out. Any help most appreciated!
