Curious... I was just trying to extract some typefaces from Coherent for the Commodore 900 (as you do :-)), and the 'Gacha' font shows up there too, so apparently Apple weren't the only ones to borrow from Xerox Smalltalk.
Now I gotta know where 'Bocklin' comes from, since that's another font which the Twiggy Macs and C900 Coherent have in common, but it's not in that Smalltalk list...
