Approximately EUR 8 including shipping. Still sealed (probably - if not re-sealed). There’s definitely some more stuff in the box like a manual and driver disc that I can hear moving around. After all, the boxes are fairly large compared to what you’d get today. I’d want to unpack them… but I also don’t because they survived so long. I don’t know. Maybe if I’ll get yet another one… Here’s a look at the entire box: 
Specs: Bluetooth 1.2 Class 1 USB 1.1 Minimum requirements: 300MHz CPU 128MB RAM Windows 98SE So what about the Class 1? Typically the devices you use are Class 2 with Tx power of up to 2.5mW and range of around 10m. Class 1 can go up to 100mW with range of around 100m. Assuming both ends are same class. Otherwise you’re just causing more interference on 2.4GHz. https://www.sharetechnote.com/html/Bluetooth_Specification.html#Bluetooth_Classes_and_Ranges It also has an external antenna giving it some cool factor.
There were also some Bluetooth APs similar to WiFi. I’ve been wanting to get one.
I have 2 pictures of this one. The green one comes from a review I wish I had archived because I can’t find it anymore and it’s possibly gone now.
But there’s a review of a similar product from Belkin: https://www.geekzone.co.nz/content.asp?contentid=1773
There’s also like 3 different Bluetooth profiles for networking. LAP (LAN access profile), DUN (Dial-up networking profile) and PAN (Personal area network).
I need the PAN one, that works fine with modern devices.
