Quadlink by Quadram

Description

PLEASE READ:
FOR PARTS NOT WORKING.
RETURNS WILL NOT BE ACCEPTED.
The PCB appears to be good condition, but is untested due to a lack of hardware to test it on. This listing includes original box, manual, Quadlink PCB, static bag, and connector cable. This listing is missing the original Quadlink diskettes, but copies of this may be available online with some searching. The box is creased in a few places, but is in good shape considering its age. The manual is in pristine condition, though its cardboard cover has a slight crease on it. Missing from the documentation is the "3.0 ADDENDUM" section. There's a curious signature on one of the manual pages though. Who could it belong to?
