Now, that I figured out the dimensions, let me modify them...
Why?
My starting point is this 17" monitor, that I got some years ago for $5 in a thrift store, and it will be operated by a Raspberry Pi (model 3 B).
It's an Acer V173p with an aspect ratio of 5:4, 1280x1024 pixels, and a screen size of 13 1/4" x 10 5/8". This is about 3 1/2" larger than the screen size of the pod bay unit - the height about one inch larger.
For a perfect replica, I could make a 9 1/2" x 9 1/2" opening in the front plate and hide the excessive screen area.
However, since a few years, I wanted to set up the Retro Pie gaming system on a Raspberry Pi but did not want to build a dedicated device (after all, to be realistic, I will not spend too much time with that). So, this is the perfect opportunity: I will add the Retro Pie gaming as an additional feature in the HAL console. And with time, I may come up with other ideas of software to run on this console. Therefore, I decide to make the full screen area visible. The HAL screens will be displayed in a limited, 9 1/2"-squared area, but other software may use the full screen.
Based on this, I come up with the following plan:
This unit is just 1/2" higher than the original prop, and 2" wider.
I will build this from 3/16" plywood (that's what I can cut with a laser cutter).
To handle the weight of the Acer monitor, I add an inner frame of 3/4" pine wood (the green area). The monitor is placed in the top right corner of this frame (the monitor bezel is indicated by the blue area). The light gray area corresponds to the monitor screen, and the dark and yellow areas to where the HAL screen images will be displayed.
For future options, I add three momentary push button switches in the slit, a USB hub (with four connectors) below the face plate, and a small camera module for the Raspberry Pi above the face plate (all indicated in red). I always wanted to play with Open CV (e.g. for face recognition), and the camera in this console could be a nice testing ground for this (imagine how nice it would be if HAL recognized me). The USB hub allows to connect a keyboard and/or game pad (for Retro Pie, to play space invaders on a HAL computer - or chess, just like Dave). And the three push buttons can be used e.g. for a tea timer (all of my computer replicas must feature one!) or to steer through some simple on-screen menus.
Here are the CAD drawings. The yellow and blue lines are just guides, indicating the placement of the face plate, the inner frame, and the monitor - these will not be cut.
I added some holes in the bottom left corner for a second speaker - with the same spacing as in the speaker grille in the face plate.
