These are very hard to find in this condition. This is the twisted-pair version with an RJ45 port (I do not believe this has any coaxial connections on it).

    Can not speak for the network functional...

    Can not speak for the network functionality. However, the card is flawless as an XTIDE ROM carrier running the 386 binary on a 486 VLB with ROM Shadow for 128GB SD Card support.
