As of today, the manual is very close to being completed in draft form. Josh and I will still need to get together to gather the voltages and resistances, as well as to retake one photo that isn't quite correct (my fault, not his).
As we speak, the majority of the parts for the Mainline are either being manufactured or shipped to us, with our custom switches, graphic overlays, and power transformers being the bits that may take a little extra time getting here.
We look forward to shipping the first group of Mainlines shortly!
