Hi Jack,

We have an early DataScope by Teletype in a briefcase complete with 
drawings and instructions in the museum collection.  It was donated 
along with a 208B dataphone.  When I get the lab set up at the museum 
this coming winter, I will have to do some researching with your 
assistance.  By 2004 we hope to have the museum moved to the old 
Naval Training Center (NTC- San Diego) that was closed some years ago.

Don

P.S.  Also have a HP 4955 Protocol Analyzer with an RS-232 / V.24 POD
