Abstract: A unique electrical connector for power and signal connections from an I/O cabinet of a control system to a block I/O assembly mounted in the cabinet to allow a blind fit of power and signal connection of power and signal connections insuring that power will be provided to the block I/O assembly before any application of signals thereto.

Abstract: A unique cabinet mounted I/O assembly adapted for integration into a control system which allows a block I/O assembly to be mounted in both sides of the cabinet allowing a blind fit of power and signal connections insuring that power will be provided to the block I/O assembly before any application of signals thereto and preventing any mismatching of I/O units to wrong processor blocks in the cabinet by a color matching scheme.

Abstract: The present invention is drawn to an I/O block (38) assembly comprises a plurality of specifically configured I/O blocks (38) mounted to a conductive column (46) providing power to and communication between the I/O blocks (38) with each individual I/O block (38) programed for a specific function requiring that the proper I/O module (42) must always be inserted into the right base (40). This is accomplished by providing a set of pegs or pins (50) individually configured on the base (40) which match a complimentary series of openings 74 on the I/O module (42) formed by a mask (70) covering a plurality of holes (60) while leaving the holes matching the pins (50) uncovered.

Abstract: A computer keyboard retaining assembly having a removable peg mounted to the bottom of the keyboard and being insertable into a spring loaded peg holder mounted flush with a workstation work surface to allow rotational and lateral movement of the keyboard along the surface to optimally orient the keyboard with respect to the workstation operator while preventing the accidental dropping of the keyboard off the Workstation surface.

Abstract: A computer floppy drive mounting assembly is made to be slidably removable from a slide casing assembly located proximately to an open slot on the front of the computer without the use of any by allowing the drive mounting assembly to have a slotted portion near the front which fits over the edge of the open slot to hold the floppy drive in the computer and which when lifted over the edge allows easy removal of the floppy drive to provide easy access to the computer fuses inside the computer to allow them to be serviced and or replaced by the computer operator.
