Control desk for TOSBAC (Toshiba Scientific and Business Computer) computer system, with keyboard and control panel, communication console with handsets (2) and cabinets for monitors (2), wood / plastic / metal / electronic components, made by Toshiba Corporation, Tokyo, Japan, 1983, used by Transgrid NSW, Australia, 1985-2003
This control desk consists of a purpose constructed wooden desk with rebates for a keyboard and control panel. The desk has a return for placing monitors, printers and other peripherals. Under the left side of the desk is a set of three drawers for stationery and files.
The keyboard situated to the rear of the desk consists of a standard alpha-numeric keyboard with added dedicated function keys to control the CPU. The control panel situated at the front of the desk has on its right side a set of keys that duplicate the function keys on the standard keyboard; and on the left side a set of buttons that display alarms and also duplicate function on the CPU.
Also included is a Communication Console with two handsets and function keys relating to remote sites - specifically Yass and Wagga in regional NSW, Australia. The console is divided into four sections. The one column of buttons on the LHS were available for control room functions like alarm bell extension and backup alarm system bell acknowledge. The next group of three columns of buttons are provided for an old 'operational switching unit' (OSU) phone system which was a backup phone network which had manual trunk selection. The next six columns were connected to direct line connections to each of the substations under the control of the operator as well as other control rooms. The right hand group of buttons accessed the VHF radio network. The handset for the radio has a push-to-talk switch.
The two cabinets for monitors are made of the same wood as the desk. They are mounted on four castors for easy movement, and have a door on the front. There are four holes drilled through to the inner cavity of the cabinets (one on each corner) to enable cabling to be recessed. There is power and computer cabling mounted inside both cabinets. The monitors sit on the top of the units.
