If you happen to have one of these smart zynq boards sitting around doing nothing:

I recommend you give this a go to convert it to a fun little console with video, audio and a video coprocessor unit:

Here's the sandpiper emulator, running all hardware and software that the real hardware can.
Kudos to QEMU for making this so easy. Adding custom devices was a breeze.
Head over to ecilasun.github.io/sandpiper/ and check it out!
(OS .img is very large but I'll find a way to distribute a copy)

sandpiper is getting a QEMU system soon. It can already boot and run the operating system and run quake as a test, I'm working on more devices at the moment.

Happy weekend folks.
sandpiper is a Linux based mini console that aims to be really simple to program games on.
Project page with documentation and links to related repos is below for a first release candidate version:

Sorry for not posting game-dev stuff. Perhaps after I wrap up some work stuff next year there’ll be time.

Yesterday I found a bunch of video output issues and while fixing that added four new video modes:
320x480 (8 & 16 bpp)
640x240 (8 & 16 bpp)
Not sure what they’ll be good for, but since the display is actually always 640x480 and uses pixel doubling, this was easy to achieve.

So far it's good, though I had to use 8 screws since I didn't want to deal with snap-fit this time around.

This older enclosure build is great but I think I could make it even smaller. Also I should have made right shift shorter instead of left so the arrows could tuck in a bit more…

I think I’m happy with how sandpiper console looks for now.
Back to enclosure design with SOLiDWORKS for a bit today, if I can stop playing with fbterm for a second.

Now, how does one add custom devices to the memory bus of QUEMU… and how much of a torture will it be to build it for both Linux and Windows?

Fancy schmancy command prompt added. Had to make a custom small one with one directory level since existing scripts do not run very responsive on small computers.

Today I wrapped up some details about sandpiper drivers. Now I don’t run into situations where apps leave video, copper or audio output running, and driver takes care of silencing sound / resetting video mode on any type of app termination.
I guess next is some more fancy instructions for the copper

I've dropped Ubuntu 20.04 in favor of Petalinux2025.1 for sandpiper since I don't need anything apart from a system that boots and takes me to command prompt.
Ubuntu requires way too much work to get versions higher than 20.04 working on Zynq 7020, if at all, and I want a more recent kernel + rootfs

Vacation time! Good opportunity to wrap up sandpiper project and start looking at an emulator.
I’m going to have to write some custom devices for QEMU it seems…
Also started thinking about ‘the next one’

All of the files to make one of these 'sandpiper' things is posted on my github. I'll add detailed documentation and more samples on first chance. Likely that the enclosure design will change.

Quake is also running at a decent frame rate without prior can issues. I think all that’s left to do is to try to get a qemu version working and finish the darned enclosure so it can close properly 🤣

Testing out the video coprocessor with a short palette update program.

Testing out the video coprocessor with a short palette update program.
Done with the video coprocessor instruction set for the time being, and it runs quite well so far.
I can now to Amiga-like copper effects on sandpiper.
I think I'm getting closer to being able to opensource this.
