The little portable 18x36 portable HVRR logging module was started in 1975 when I headed to college, that thing fit on top of my dresser I took with me. That's still running as you can see, although it shows its vintage. The Santa Fe second layout - my current one - is shown here as of 1983: http://www.randgust.com/atsfplan.htm And this is the way it looks with the final level over top of that hidden storage yard pretty much today: http://www.randgust.com/U36C 8714 Flagstaff sm.jpg
Not officially, but let's just say that they did not exactly sell like hotcakes. It looks like they'll keep the line as a niche product, but won't exactly expand it to the same coupler variations as the standard Magne-Matics.
