Well my third 1200 arrived yesterday, and its keyboard restore went well this AM,
So now it's probably time to post the numbers.
latest is Taiwan 72R DA 24420 253 Board sticker DA 213 REV. A, underside label JUN 18 1983 B, lucky enough to score the matching serial box with it.
earlier is Taiwan 72R DA 18824 223 Board sticker DA 223 REV. A, underside label JUN 02 1983 B
my first was USA 83S DA 015042 043 no Board or underside stickers, keyboard has been butchered by prior owner(s) and remains in abject disrepair.
I think I'm done now........... at least for this year . Happy Holidays Everyone!
