Can't find the original Rasp Pi 1 image for download

Hey guys. Trying to get my old Batendro up and running again and have found that the original SD card is corrupt and therefore it doesn’t boot. I therefore went to install a new image on a new SD card for the Raspberry Pi and found that there is no download for one anywhere.

Would appreciate getting hold of the original image for the Raspberry Pi 1.

Thanks!
