Computer Board questions

So I got a box of old PCI cards and various cables at a thrift shop today. Mostly old modem cards, add-on USB, a video card, etc. But I have this one card its made by Elektronik Model PCEY-111. I did a quick ebay search there are 2 of them up for sale for $397 out of Pakistan, but nothing else. Google doesn't have much either, nor the manufacturer's website. Any ideas on what it is?

I also have another card that raised an eyebrow. It looks to be a Pci To Pcmcia Adapter, am I missing something or these dudes crazy $500

They are indeed crazy. When researching the value of an item on E-bay, the only thing that matters are completed listings. On that p2cb485 if you click on completed listings you will see that they do NOT sell even at $5

Indeed and you will notice all sorts of abnormalities in all categories such as that absurdly priced card. Parrot is correct check those sold and completed listings and look at active vs sold on a rolling basis it may not even be worth the time to list.
