Lexmark-made 122-key host-connected (terminal emulator) keyboard for Better On-Line Solutions (BOS), presumably for PC/AT and PS/2 compatible computers running IBM 5250 compatible terminal emulation software. Like IBM PS/2 Host Connected Keyboards, this one has various blue sublegends to differentiate PC-only functions from terminal/universal ones. These had a modular SDL to PS/2 cable.
