I'm currently remote-assisting a friend in Australia with getting a model 500 assessed, and back on track — to working condition. From a sticker inside the case, this apparently was a former model 300 having been RISC upgraded.
We're currently scratching our heads over two SPD "books" with the feature codes #2677, and one #6051. Can't find those FCs in any System Builder PDFs of that era, and online sources are either possibly misleading (#2677) or outright unavailable (#6051).
Do these FCs ring a bell for someone? Thanks!
:wq! PoC
