Hi!
I have a Macintosh 128K (a European version, 220V) which is converted to a 512K. It looks like just te chipset has been upgraded, but is it done by Apple (see attached photo)?
The chips are branded with NEC so that makes me suspicious that it is not.
Is this an original Apple-factory upgrade from 128K to 512K or is it done by someone else?
Do you have any clue what the “Apple 16” sticker (round, white with red apple logo) on the large chip might mean (see photo)?
Best regards,
