Doing some spring cleaning of the mountain of PC-related parts in my basement. I have a number of 16/4 token ring cards. Most were pulled (working) from machines that were upgraded to ethernet at my place of employment. Several are brand new. A mix of Dell and IBM. There are at least 15 of them, possibly more- I can provide an exact count if interested. I just don't have a use for them and it's not worth my time even trying to ebay.
They should fit into a USPS priority mail fixed rate box. If you could use these, pay postage ($8.10), and they are yours.
