Yes, but this auction does list a Hyperdrive Mac. It is interesting though how 7 people have bid up the price to nearly $1300 in spite of the fact the seller says the Hyperdrive is non-functional. It this thing sells for that, my "working" Hyperdrive Mac would surely be worth more (not that I would dare sell it, mind you).

It's also very funny to read the top part of the listing:

Steve Jobs said back in 1984 that it couldn't be done. That is, install a 10 MB Hard Disk into a Mac 128k... Well General Computer said it could and they went on to build the HyperDrive Mac.

Now skip down to the orange paragraph for this:

General Computer installed the 10MB Harddisk and added the 512k expansion memory.

Steve Jobs was right: this isn't a 128k Mac with internal HD. Even so, the photos are interesting. And the shot of the face of the drive mechanism looks exactly like the face of my Hyperdrive. The jury is still out on exactly what my drive mechanism is though. (I'm looking for more historical technical wiki on this drive mechanism than just "it's got an MMI lable, so it's an MMI drive". But as H3NRY pointed out in a previous post, MMI was short-lived so there are probably no photos available of the drives they made. If there was photo and a model number associated, that would be a good enough "DNA match" for me.)
