Well
am a bit lost in the 90's Series genealogy. C90A, C90B , F90 ...
I have a global picture, but I would like to know more about this serie.
Is there, somewhere, a clear history of the variants, evolutions and upgrades of this wonderful toy ?
Am regularly asked about the one am flying : "Which model is it ? B or A ? " Haven't got a clue, especially when specialist disagree themselves
Mine is a 1979, LJ-867 , Does it ring a bell to you, mighty techies
