I'm trying to get some historical geographic information from Wisconsin and have been pointed the way of the TIGER/Line Shapefiles. Unfortunately, they're in a strange format (see, e.g., the files for Adams County from 1992 [.zip download link]), with file types like .F5A (a set of files of type .F5{x} where {x} is one of A, I, P, R, 1, 2, 3, 4, 5, 6, 7, 8).
This is quite foreign to me, but I've seen it suggested that it may be possible to convert these to modern shapefiles.
Is there a robust way of doing so? (It goes without saying I prefer a free option)
Alternatively, how could I open the file in a common GIS program (QGIS, SAGA, or R), whence I could convert it within those programs (or at least view the polygon boundaries, which is a step in the right direction)?
