Posted by: Huxley on 2020-11-10 08:34:04 Oh awesome - thank you, @oldappleguy! I found a PDF of that manual early yesterday but the copy I found was not scanned especially well, and the details were a lot harder to make out - yours is much clearer! Excited to keep making progress with this 🙂 Huxley
