Vintage U.S. Robotics Megahertz 128k ISDN pc card, new in box factory sealed

Description

For vintage electronics and computer collectors, this auction is for one factory sealed US Robotics 128K modem pc card.
This unused item was for use with Windows 95 or MAC OS.
Because it is still sealed, this item is untested, but it is a certainty everything that should be included is still there.
This item is being sold as a novelty/collectors item only. It is not compatible with modern computing systems.
This was probably was a pricy item when originally purchased, and I would imagine very few are around today.
Please note I ship on Friday, Saturday, and Monday only due to work obligations.
