Linux Mint 17.1 MATE 32-bit? https://archive.org/download/linuxmint-17.1-mate-32bit.iso/linuxmint-17.1-mate-32bit.iso but is not supported so... maybe not?
I didn't find any MATE 32 bit but there are alternatives https://itsfoss.com/32-bit-linux-distributions/
and I mentioned Linux Mint - but they are no longer supported. You could also try LM LMDE, but that only has Cinnamon desktop. Not finding a ton of 32-bits using MATE. MX Linux was supporting it, but not sure if they still are.
