Same here. The FE came prepared with a replacement board. Never repaired the board. In and out!
Which makes sense. My guess is in the 80's 90's they would send the board back to a rework facility and repair it there. BGA/PGA is not too difficult to do if you have a good rework station, and the rest of the chips on the board were probably worth enough to make the rework totally feasable.
By the mid 2000's, yeah they probably would just trash the board. C
