The EA-500 Share Talk is a communication device that's easy to connect. It's a discontinued, out-of-production item, and is no longer listed on the manufacturer's website. Over 15 years ago, I used it to share files between old Macs without LAN ports and DOS/V machines via Win mounter. I've only confirmed that it powers on, as I no longer have an environment to use it in. It's an old item, so I cannot guarantee that it will function properly. The box has some wear and tear. - Model: EA-500 Share Talk - Power Supply: DC 5V - Brand: REUDO - Type: Communication Device Purchase is OK with immediate decision. Thank you for looking.
