The device looked like this initially (the top and bottom covers were missing):
The leftmost card is missing (it was already removed). The display is at the front.
From this position I am numbering the cards from left to right, starting at 1 and ending at 21. Card position 19 is empty (there is a slot on the front rails but not at the end). After removing all cards we are left with the empty chassis with number markers for all cards:
In the empty chassis picture you can see the bottom card mount being crooked; in fact its screws were missing, and it is slightly bent.
I removed all cards first, and wrote down all connections from card to card. For this I number all gold coax-like connectors on each card starting at 1 for the topmost one, and going downwards. Some cards have connectors in odd places so these are marked as such..
The device contained the following cards:
