These are definitely no original Doepfer modules resp. bus boards. Our bus
boards are equipped with 16 pin connectors only (there was no change since
the beginning) and the modules are equipped with 16 or 10 pin connectors.
There exists no Doepfer module or bus board with 14 pins.

More information about the type of connectors used in the A-100 can be found
in the A-100 user's manual (introduction chapter, page 4-6) and in these
documents on our web site:

All modules are shipped from the factory with ready assembled bus ribbon
cables so that normally the customers has not to deal with the connection at
the module but only with the bus board connection.

And I cannot confirm any problems with loose connectors neither at the
modules nor at the bus connectors. During the last 8 years I never heard
about a loose connector (provided that the connection was made in the right
way). If anyone had problems with loose connectors please let me know.
