FP11-C modules found! Just missing the cache boards: M8142, M8143, M8144, M8145. Any help finding those is appreciate, they are needed to restore a PDP11/70 computer. Thanks
If you can get to face book he posted a picture of boxes with the exact boards you need. His profile says he's from Montana. More digging. Based on a post there I'm thinking you already know about this.
