Doug,
I got minor problems from installing a RS422 port in the (modem?) blank,
which if you make it a tight fit can deform the top half of the case and
back slightly. Tolerances were tight, and this caused pen problems, and
creaks when pressing on the case. After removing some material from around
the RS422 port, everything was good again. Marco installed a RS422
port. Maybe he had the same thing?
Cheers,
Damien
