Abstract

This article describes a stacking plate structure with grounding spring appendages for holding disk and diskette drives in any drive-retaining compartment of an IBM PC XT system. The interchangeable stacking plates disclosed herein permit direct- access storage device (DASD) commodity integration of 5-1/4", 3-1/2" floppy diskette drives and 5-1/4" hard files (full and half-high configurations) into an unadulterated IBM PC XT base frame and covers. The DASD commodity-stacking side plates are shown in the drawing and utilize existing mounting holes in DASD commodities to stack and fasten two such devices, or a combination containing a blank, into a single assembly while remaining within the predefined IBM PC XT base frame opening (compartmentized envelope).

Direct-Access Storage Device Commodity-Stacking Plates

This article describes a stacking plate structure with grounding spring appendages for holding disk and diskette drives in any drive-retaining compartment of an IBM PC XT system. The interchangeable stacking plates disclosed herein permit direct- access storage device (DASD) commodity integration of 5-1/4", 3-1/2" floppy diskette drives and 5-1/4" hard files (full and half-high configurations) into an unadulterated IBM PC XT base frame and covers. The DASD commodity-stacking side plates are shown in the drawing and utilize existing mounting holes in DASD commodities to stack and fasten two such devices, or a combination containing a blank, into a single assembly while remaining within the predefined IBM PC XT base frame opening (compartmentized envelope). The restrictions of these openings are overcome by choosing a material thickness that is thin enough to remain within the envelope yet maintain the structural integrity of the assembled unit to satisfy dynamic loading. Stainless steel can be used for this purpose. Each stacking plate has two spring appendages that ground the assembled unit to the base frame assembly. Upon insertion into the main frame, these springs provide a fresh wipe on the masked grounding area of the cage within the frame. These plates are interchangeable left to right. In addition, the plates function as a spacer filler- plate for DASD commodities by maintaining the vertical separation...
