Really enjoyed the latest Access on podcast from the NFB about the early years of Apple with the apple Ii, particularly about my beloved Apple iIE and the echo synthesiser. One slight correction that I think I'm wright in making is that it was Berkeley Systems that produced Outspoken for the Mac not Alva.

@Woody Alva bought Berkeley Systems sometime in the mid1990's.
