You can take the simple route and use a Pi Zero with the PigFX terminal emulator and a Serial Hat, or you can go the more advanced path and use a Pi 3 running Cool-Retro-Term and a USB-Serial adaptor. The keys light up, but they can be turned off for a period feel. A nice clicky keyboard, such as this one from Amazon.An LCD screen with HDMI input, preferably with a 4:3 display ratio, such as this one from Amazon.Check out the left-over scraps box in your local plastics supply store. I used 3mm acrylic in white and semi-opaque black. Enough acrylic sheets to cut out the required shapes.Don't trust my plans over your own common sense! It can get expensive to keep re-cutting acrylic if a mistake is made. Note: Please triple-check the panels are exactly as you want them to be. If you have a branch of company such as TAP Plastics nearby, go in and have a chat to see what they can do for you. If you don't have access to a laser cutter, it's possible to submit plans online and get pieces in return from mail-order companies. When cemeted together, this produces a solid unit that can withstand an 11-year-old playing Zork.

Rather than 3D print the pieces, I designed them to be cut out of acrylic using a laser cutter. This is a possible solution if you need a dedicated display for a retro-computer kit (for example, an Altair-Arduino, PiDP11/70 or RC2014 ), and don't want to buy a used DEC VT terminal from eBay. This is a brief description of how to build a retro-styled terminal, using a USB keyboard and a Raspberry Pi with serial adapter.
