A integrated vacuum pump desoldering tool is the only effective way to extract the displays. There is more to component removal than just buying the appropriate tool, technique is just as important. While it is very dated, this video provides an excellent overview of the process as it applies to older HP through-hole boards.

Dated maybe, as you wrote, but very impressive, thank-you for sharing.
