FARM USE 1979-
Used on farm vehicles which only travel on public roads for "short distances".
1979 BASEF-G10A - FN-99Z
Around 1981, the blue (1979) base plates started being issued, the numbering stayed in the same series.
After switching between FA-00A and F-A00A a few times, the separator finally wound up after the 2-letter prefix.

Starting in 1992, 7-digit Farm Use plates were in use for a few years.

After the 7-digit plates were discontinued, the FA-00A series resumed - possibly in 2000 ?
The sample plate below was issued on the Avery base. The numbering sequence was never used, and I don't think any regular-issue plates were ever produced on the Avery base.
3M2 BASEFT-10A - FW-99Z
It appears that the FX, FY, and FZ series were skipped.
The next series started at GA-10A, dropping the "F" prefix for farm, but retaining the 5-digit AA-00A format.
No flat Farm Use plates have been seen yet.
