The upgrade consisted of replacing the drive assembly, plastic front
bezel, boot EPROMs on the CPU board, and disk controller EPROM on the
I/O board. The upgrade kit was sold to dealers and fairly expensive,
but they got the entire price refunded when they returned the old
Twiggy drive assembly to Apple.
Apple destroyed the returned Twiggy drive assemblies.
Someone suggested that Apple knows how many machines were ugpraded.
Back in 1985 they undoubtedly did have this information, but today
there is basically zero chance that they still have it. Information
like that is not preserved very long.
