Acrylic X3L case for the Omega Home Computer

Omega Home Computer XXXL Acrylic Case

Acrylic case of size XXXL, from now on X3L, for the Omega Home Computer.

Introduction

This is a new acrylic case design¹ for the Omega Home Computer based on Capsule5000 XL version, specifically on the Omega-Eco2_SME_51mm_simple_22_09_2021_slot_trasero.dxf design, adding the following extra features:

• the dc-adapter 1.5-1.6b can be installed in the "inverted-power-barrel" configuration without colliding with the floppy disk drive
• the dc-adapter can also be installed in alternate locations using a panel mount power connector (or even the "anchored-switch" configuration)
• a bigger cutout allows to accomodate the larger rectangular form of the power SPDT switch 3-pin copper used in the dc-adapter 1.5-1.6b kit
• taller ESR capacitors can be used, with or sans the multimedia hat, without colliding with the floppy disk drive
• extra space bellow the floppy disk drive allows a taller and full length heat sink to be installed on top of the VDP if required
• new vent holes below the motherboard VDP footprint are provided for better air flow
• the floppy disk tray is secured to prevent vertical movement irrespective of the floppy disk drive height
• the reset switch has been moved to the keyboard plate, in line with most MSX computers equipped with a reset switch
• all connectors are labeled (using the MSX font)²
• the Omega and MSX logos are also incorporated
• (need to be tested) the floppy disk tray has been re-designed trying to remain compatible with the F4/FMPAC v2 hat
• (need to be tested) enough clearance has been kept trying to remain compatible with the O4MEGA v2 hat
• a companion tray has been designed to ease the placement of the dc-adapter 1.5-1.6b (which lacks screw holes on the PCB)
