Since about 1978. In those days, many vendors were selling clones of FIG-Forth for various personal computers with very little value-added beyond the boot loader and a little hardware interface. I started off with one such on my 6502-based Ohio Scientific C1P. http://doublebit.com/archives/software/challenger1p/
"Organizer" may be too strong a word.
Wonderful people, great speakers, lots of Forth.
