Would you believe I found an even older resource pack backup from February 2011? This one seems to coincide with Minecraft
Beta 1.3!
I've bundled up a bunch of the packs I found that predate the git repo history, attempted to organize them by version, and put them here:
AppleNovaBradTextures-archives.tgz
It's hard to imagine now that these were all the items and blocks we had back then!
No shears! Were we just farming and murdering sheep left and right to get blocks of color?
