Raspberry Pi 400

I’m fairly new to the pi universe. I have a 400 (built in keyboard) running Raspberry pi 64 bit OS. I can’t seem to install either flavor of HAMRS (Ubuntu or Raspbian). I’m still unsure of the differences between the OS choices though I do suspect they aren’t entirely compatible. Do I need an older OS (Raspian) to run it? Thanks for your time!

I wasn’t successful getting the older HAMRS to run on my RPI4b with Raspian Bookworm. I don’t recall if I tried older OS releases. The current Beta Web-based version does run there. There haven’t been any Beta binaries that run on the RPI yet.

Wanna be a guinea pig?. Here’s a fresh build for ARMv7l:
