BA11-K CHARACTERISTICS
AND SPECIFICATIONS

1.1

GENERAL

The BA11-K is a 10-1/2 inch expander ‘box Wthh is.

There are two basic versions of the mounting box: the
‘BA11-KE for 115 Vac, and the BA11-KF for 230 Vac.

These two variations are the result of two ac input boxes,
one for each line voltage. The two ac input boxes can be

mounted in a standard 19-inch rack. Itis designed to house

the Digital standard system units that make up a PDP-11
expansion system. The expansion system (expander box)

interchanged within the same BA11-K mounting box with

no other modifications.

can contain memory, peripheral controllers, devices, or

options compatible with the PDP-11 family. The BA11-K is
