Original Programmer/Interrupt switches pulled from working Mac SE and SE30s decades ago. They are yellowed, but all clips and pins are intact. The batch is a mix of815-1008-A and815-1008-3 part numbers which are functionally identical. You will receive a random selection of one of the part numbers. I've had them sitting in a bag with all of my other vintage Apple stuff for too long - time fore someone else to make use of them. Thanks for looking.
