Digital Transport Adapter

This is a Comcast "Digital Transport Adapter Self Installation Kit." It may be 20 years old but has never been used and is still in it's box. At the time, Comcast carried two signals, analog and digital. Analog did not have the necessary bandwidth and they were switching the analog signal portion of the network to their all-digital signal. This adapter allowed you to receive all your channels at that time. I don't know anything about electronics but I thought someone (electrical engineering student?) might be interested in such a device. But maybe not. Just thought I would post this before throwing it away.
