I'm confused; I've got at least one TS-2624 board which is identical to yours and also several TS-1s and TS-1SPs, but they all had the backup battery in the power supply so, although the power supplies were damaged, the Main boards were not (although it's amazing how far the corrosion can migrate).

The TS-1s and TS2624s were very similar but certainly not the same board.

I've also got some of the newer Fame style models; guess I should look at those but if they have the pox then it's probably too late.

FWIW, I've also got a bit of documentation for these and various other Falco terminals (User, programming & service) but alas, not for the 2624; I can also certainly dump any firmware that I have.
