Abstract

This article describes a stacking and packaging mounting assembly for positioning combinations of 0, 1 or 2 direct access storage device (DASD) units into a personal computer (PC) enclosure without having to alter the enclosure hardware. (Image Omitted) A combination of special 100o flat-head screws, stacking plates, and the various DASDs comprise an assembly that allows for placement of 0, 1 or 2 commodity units within a single envelope of a PC base frame assembly. Commonality of datum planes between DASD commodities and trays permits interchangeability between the commodities that make up an assembly which in turn are interchangeable between the left and right compartments of the PC frame, as illustrated in Fig. 1.

Direct Access Storage Device Commodity Assembly Integration Into the Ibm Personal Computer Xt Envelope

This article describes a stacking and packaging mounting assembly for positioning combinations of 0, 1 or 2 direct access storage device (DASD) units into a personal computer (PC) enclosure without having to alter the enclosure hardware.

A combination of special 100o flat-head screws, stacking plates, and the various DASDs comprise an assembly that allows for placement of 0, 1 or 2 commodity units within a single envelope of a PC base frame assembly. Commonality of datum planes between DASD commodities and trays permits interchangeability between the commodities that make up an assembly which in turn are interchangeable between the left and right compartments of the PC frame, as illustrated in Fig. 1. The identical frame attachment methods across the line of DASD commodities maintains positive grounding, thermal capability, and acts as an EMC shield for said units, as shown in Fig. 2 and in the pre-assemble illustration (Fig. 3). It is the internal mounting techniques of the DASD assemblies that ensures maintenance of the PC hardware and base frame assembly (See Figs. 4 and 5). Installation of the picture frame presents the PC family appearance in conjunction with the various DASDs. A special slide in and out feature has been incorporated into the DASD assembly to aid manufacturing by not permitting the assembly to fall out of the CPU during the...
