Abstract: An open office system partition panel assembly including a panel having an outwardly opening wire raceway channel on top with a removable cap to permit wires to be laid in the top raceway channel. End wire raceway channels open away from the core of the panel and each has a panel connector support rail closing its opening. The wire raceway channels form a steel frame of box section strength for the panel and all metal-enclosed, non-snagging wire raceways from the top to the base of the panel. Legs formed as part of the panel base support the panel connector support rails. Wire passageways extend from the panel base to the end wire raceway channels. The panel base has an end section fastened to and supported on each leg. Upper panel connectors facilitate the connection of panels, improve the rigidity of the connection between panels and provide positive locking for the panel connection, both vertically and horizontally.

Abstract: A base assembly for an open office partition panel. The base assembly is formed in sections, namely, end sections and a center section. An end section is fastened to and supported on each leg. The center section, which fastens to and is supported on the end sections, may be omitted when electrical wiring is not installed in the panel base. Each section is formed of a pair of elongated, channel-shaped housings which are fastened to each other back to back to form a housing section having a center dividing wall and open sides. A snap-in divider separates each channel-shaped housing of the panel base section into upper and lower wire conduits.

Abstract: A memory expansion apparatus is disclosed which provides for expansion of memory capacity by use of logic associated with memory modules. The logic provides for selection of one of a plurality of pages, each having substantially the same address therefor. The device provides for the selection by utilization of a special instruction, and includes decoding means for specialized bits in the instruction. Means are provided wherein repeated access to the same page in a block occurs free of a requirement of repeated address decoding amongst the plurality of pages in the block.

Abstract: A master keyboard terminal is provided to communicate with a programmable control unit. Auxiliary keyboard terminals are connected to the master terminal, and utilize a substantial portion of the logic circuitry located in the master terminal. Auxiliary terminals may be scanned by the master terminal and data entered on the auxiliary terminals are communicated, through the master terminal, to the programmable control unit.

Abstract: The prolonged depression of a cursor scan control key on a CRT terminal keyboard generates a unique coded signal that is fed to a gating circuit. Prolonged depression is further detected by an astable circuit that generates repeated enabling pulses to the gating circuit so that the coded signal is repeatedly transferred to a separate programmable control unit. The unit is programmed to translate the repeated signals to a cursor scan command for a CRT which forms a part of the terminal.
