I’m not expert in authenticating these things, but if Jocksitter Dragon or someone else happens to be reading this, this auction is a bit over a day away from concluding, and purports to be the following:

AKALABETH – a.k.a. ULTIMA 0

California Pacific Company – Edition I – works with Apple IIe 5.25 Floppy Disk

Including Castle Version of the Game & Cover Artwork.

Works just fine & 100% playable.

I don’t think there are any bids on it at present, and the starting price is $100. I’m also not an expert in appraising such things, so I don’t know if that’s a good price or not. But there it is, even so.
