AST RESEARCH TECHNICAL BULLETIN TB-0156 3-07-86
AST-5251/11 BOARDS WITH IBM 3179 TERMINALS
Installing an AST-5251/11 board on a port from the System 34,
which already has existing 3179 terminals on it, requires the
following procedure. If the AST 5251/11 board is to be the last
physical device, normal installation procedures should be
followed.
If the AST-5251/11 board is physically located anywhere else
other than the end, it is recommended to put a terminator plug at
the end of the line.
Failure to do so could result in the 3179 terminals going out of
service whenever the AST emulation package is executed.
