[GreenKeys] Strange Teletype Corp Device

[John, W9DDD]

This item appears to be based on the MXD Transmitter Distributor.  Some 
documentation (1137B starting around page 20) on the MXD contains 
information on a MFD and MFDB. The MFD is called a "Transmitting 
Distributor"  as opposed to the "Transmitter Distributor" MXD. The 
difference between the MXD and MFD is the MFD doesn't have a tape 
reader.  The MFDB base doesn't appear to be the same as the one pictured 
on eBay.
