I keep thinking that the "via" you are stating is the jumper/solder filled grommet to the other side of the board and not the 6522 "VIA" or other chip Mac uses (VIA = Versatile Interface Adapter chip, the 6522 is also used on the 8bit  Commodores and Ataris).
Correct.  "vias" are conductor lined holes in the circuit board which electrically connect traces from different layers of the board to each other.

A "blind via" is a via which penetrates one or more layers of the circuit board, but not all of the layers of the circuit board.  So it does not go all the way through.

In this case, there's a nice fat via just a few millimeters north of the lifted pad and a fat trace that once connected the via to the pad.   So there are many options for recreating the broken connection.
