Whenever we report on a device receiving an unofficial Cyanogenmod 10 port, more often than not, it’s for a relatively recent device. But in this case, the device that’s received the CM10 build is in fact the Samsung Galaxy GT-I5510. Released back in late 2010, the device has only 512MB RAM and a 600MHz processor, making it a somewhat surprising, and indeed impressive candidate for CyanogenMod 10.
The dev responsible for bringing us this ROM is XDA Forum Member Ajay191191, who has built the ROM from source. As can be expected with a device of this age running CM10, there are a number of issues to be aware of.
All other major functions should be working normally, so the ROM is very much usable, though the dev mentions there will be instabilities.
If you want to try out Cyanogenmod 10 on your Galaxy I5510, check out the ROM thread.
