300 baud acoustic coupler

I finally brought my old modem from home to show and tell here at work.

I think it's 300 baud and has a switch on the back to go between full and half duplex.

Remember when ear pieces on phones were round?

I used this at my first DP job to get orders from Wal-mart and Kmart. (This isn't the modem I talked about in the previous blog)
