SN1200-1399 Builder's Portal

Here is the assembly manual for S/N1200-1399. It's based heavily on the old manual but we've made some changes mostly in the final assembly section. This manual also contains instructions for assembling/installing the QSK board but it assumes that you are installing the QSK board with the original build of the Hardrock-50. If you need to retrofit a working HR50 with the QSK board, let me know and I'll get some instructions put together.
