IBM Personal Computer 3278/79 Emulation Adapter

There are two versions of 3278/79 Emulation Adapters in use. The
long adapter is the earlier design and has no jumper or switch
settings. You can install one early version adapter per system
unit. The later, short adapter version has a switch bank, and up to
four adapters of this version can be installed per system unit. See
"Federal Communications Commission (FCC) Statement" on the
inside of the title page.
Warning: The early, long adapter version of the 3278/79
Emulation Adapter cannot be used in the same machine with
the later, short version, nor can the long adapter be used with
the IBM PC 3278/79 Emulation Adapter Distributed Function
Terminal (DFT) Device Driver.
Note: The connector extends beyond the bracket. Rotate or tilt the
adapter to install it.
