That is an excellent technique, and I don't recall having real problems
lifting the pin from the Vcc or GND holes (signal pins are easy) - I

install a socket.
I think I had to resort to heating one side of the board and sucking the
solder from the other side - much easier with the board in a vise.

It was tough getting the
old EIA chips out to mount sockets (must have had heavy copper
inner layers on the mainboard PCB),
I haven't repaired any VT100 or VT220 termainals, but in general I've
found that removing dead parts from boards like that is easiest if you
remove the part with diagonal cutters first, then desolder the pins
individually.
