Power on, caps lock flashes, power off without screen activation. Machine as a whole is toast, but it's probably just one failed component; doesn't get far enough to try to read the HD, so that could still be salvageable.
Depending on when Tetra Master got dropped, I might have the goods on the machine that replaced that, but that doesn't power on at all; if I'm lucky, it's just a drained battery, but I don't know where the charger is to find out.
... so, in checking timeline to decide whether that's worth doing, I discovered that the Final Fantasy fandom wiki (I know, ew) has a sheet showing all the cards. It's low-resolution, but it's something?
