That's normal. I have a working 380 (well, last time I powered it up) and it
has the same three empty sockets as yours.
The description of the error code isn't very clear. It might mean that the
card is detected (slot present register says there is a card) but the attempts
to read the card ID code and associated selftest ROM failed. That would
explain why the second line is 177776 rather than the card ID (000401).
You might need to clean the connector contacts (connector and backplane) and
also check for damaged contacts.
