[GreenKeys] MSI 1100 Acoustic Coupler

[John Lawson]

This is an MSI Model 1100 data coupler of some kind - it is either RO or XO; there's only one transducer in a spring-loaded carrier - obviously you stick the telephone reciever in it. Might be a transmitter, since there is a notch for the handset cable, and that typically exited on the 'talking' end.

Condition unknown - Free To Good Home - I pack free, you cover my shipping costs. Typically FedEx or UPS Ground from Me to Y'all.

Ship to CONUS Adresses only.

First Speak; First Gets.
