I have an early Apple II plus that looks like it was delivered for use with 50Hz/230v. It has the 50Hz jumpers set, different crystal, and a 115/230v switchable supply. It also has the PAL card sticker over slot 7. Looks like the keyboard has been replaced with a newer one along the way, I suspect to support the lowercase mods easier?
When did the Europlus models start? This seems like one but before they labelled them as Europlus's?
