I have a very old VIC 20 with PETSCII keys (I think that's what it's called). The Shift Lock switch is not working. It's throughly stuck when pushing it down. I know that later VIC 20s have different switches. I have 2 more in my collection, one older one still with 2 prong power and the newer style.
I was hoping that perhaps somebody knows where I can get this type of switch or if there is some C64 model that uses the same.
Thank you!
