I picked up this rarity on ebay, its a Katz Media prototype. These atmarks were due to be released in Europe by Katz Media, Apple pulled the plug before they went in to production . It came from a seller who, I assume used to work for Katz Media. About two or three years ago he sold off all the old Pippin stock he was still holding. He sold off about 10 brand new boxed atmark developer systems, he also sold off the prototype systems and parts. I bought as many of the prototype parts as I could afford, I ended up with the above atmark unit which has the very rare KINKA Pre-Release ROM installed as well as the HD, a prototype floppy dive, prototype 16mb RAM card & prototype controller. Since then I have picked up a number of other items for the Pippin mostly from ebay.
The Pippin was never meant to be a fully fledged computer, it was designed primarily as a gaming machine. Hard drives would have added unnecessary cost & complexity, would not have been needed by most users and may have been seen as steeling sales from Apples main stream computers. Pippins do have 128k of flash memory to store game scores and saves.
I don't know but I have a feeling my unit may have been an engineers "breakfast club project", the seller claims it was the only one made. When I booted it for the first time I found the hard drive had word a processor, email client, internet browser and some what look like beta children's games on it. It also had a loads of saved emails and internal documents from Katz Media. I deleted it all apart from the games. I'm guessing some engineer have been using it as a test machine as well as for his daily computing needs, maybe even the seller which is why I deleted all the documents.
