New youtube video showing improvements to the build (1/20/23)

Designed over the course of DOScember 2022, this build went through a few design choice changes.

(click on images for larger image.)

Originally, was designed around a Raspberry Pi 2B.

Then, was redesigned after discovering that the Dell WYSE 3040 thin client would fit inside the design perfectly.

The finished product has multiple files, The original top case with separate 5.25 and 3.5 bays, which the 3.5 bay is designed to hold an SD card slot. The power button is 8mm diameter, so you can use the model for an authentic button or an 8mm panel mount switch like I wound up doing. The alternative top case has the 5.25 and 3.5 bays built in so you don't have to print them separately. It also contains a 5mm hole for an LED on the left, and a recessed 1cm x 1cm square for a tiny case badge. There are two versions of the bottom case as well. One for a full size Raspberry Pi, and one for the WYSE 3040 motherboard. The WYSE design has the standard ports as well as a spot to put a USB to PS/2 adapter.

In my current build. I removed the front USB 2.0 port, and added header pins. Then added some dupont connectors to the PS2 adapter, so I could disconnect if I need to remove the board.

Here is what the build looks like currently

This is using the new case design, with the inset PB logo, a tiny 'intel inside' sticker (10mmX10mm), and the addition of the LED hole for power light. Also using an 5" Eyoyo S501H monitor (VGA, HDMI, RCA in)

I am running NTDEV's Tiny10 21h2 x64 (download) version on this build. The WYSE only has 8GB of onboard storage and 2GB of RAM, but it runs great. I disabled hibernation and page file, and compressed the disk to have over 2GB free space. Plenty for DOS and Win3.11.

I have a registry edit to allow auto login, another registry edit from embedded windows that skips the login screen completely, and then a scheduled task that loads DOSbox-X on login, right into full screen. Besides the OEM Dell logo in bios when it boots, it'd be very hard to tell what this machine really is. You see the Dell logo for a moment, then the PB logo, no loading swirl from windows, and then bam, right into DOS. Now I have a custom DOS boot process, check out the new video at the top of the page to see. Going to add the EXE file here soon, as well as the QuickBasic 4.5 code.

Upgrades and tweaks that are coming soon:

  • (done) 90 degree 3.5mm headphone adapter + 6 inch 3.5mm male to female panel mount adapter, to have an audio jack in the rear
  • (done-ish, left it internal to add usb flash drive for extra storage) 90 degree USB 2.0 panel mount cable to move the remaining front USB to the back
  • (done) Replacing the top case with the new model
  • (done) 5inch LCD monitor to fit the theme
  • (done! see pic above) Tiny speakers which I am currently building. They will need paint and a 3watt amplifier is on the way for that
