    Update for everyone .... me and Jason and Doug (dmemphis) all huddled; turns out Jason's post about what the contractor told him is deprecated information. The latest is that the contractor will likely sell whatever he can, but he promised VCFed (via Doug, who I authorized to act on our behalf) that we'll get a chance to do any serious data imaging, etc. before the mag tapes and any other media/documentation are forever scattered to collectors. I assured Doug that VCFed (and the "Jason Army") will help provide any resources needed when the time comes (transportation, storage, funds, technical expertise, etc.)

    Sooooooo, all any of us can do now is wait. Doug remains in contact with the contractor, who has the next move.

    Nice to hear that someone is handling everything with precaution and consideration. Nowadays, test wafers tend to contain more than one IC, so I would have looked closely on each of them to see if theres something unusual. Even partially processed wafers or scraps can yield lots of information from how things were handled at MOS/CSG. We really don't know much about how things were done there, except from the few interviews that floats around.

    PS: electron microscopes use high energy electrons and will quickly change magnetic media/domains. I have heard that STM (scanning tunneling microscopy) can give magnetic information, but that may be a very tedious and long task (they are quite slow).

    The tapes and disks are probably not more than 30 years old. Child's play using traditional data recovery, even with environmental issues like fungus infestation.

    No need to go the STM route on something this new. Just treat the media with due consideration for its history.

    Ok. Ultimately my point was though that the individual coerced areas of a floppy disk isn't too small to be see. I was told smaller then the wavelengths of light. I doubt it.

    WOW to this thread. I live nearish to the site, could have insinuated myself into the recovery process early on had I logged in before.

    One question: does this guy, who says he doesn't know much about this stuff, really think he tossed a half dozen C65s? How would he even have been able to ID what they were?

    I don't know the answer, but rest assured, we're on top of it. ("We" = the non-profit organization that owns this forum.)

    On a floppy disk, even an ED one, not even close. You can see things clearly with some magnetic developer and even a moderately powerful optical microscope, which on an ED floppy a feature is only about.02 thousandths. On 1/2" 9-track tape recorded at 800 NRZI, you can make them out them with a watchmaker's loupe.

    That is great...It certainly makes me feel better. He most likely tossed some C64Cs is what I like to think because the other option is just too disturbing given their rarity and recent value.

    Oh sure, I didn't mean to suggest I'd be there to take stuff. Just would be fun to be involved in recovery and cataloguing and frankly just seeing this "warehouse find" - one dreams of such things!

    I have attended the VCF East the last several years and in fact contributed to the mega Commodore exhibit last time (a 1551 drive).

    If I threw out something worth $100K+, I'd be at the dump digging through the trash to find it...
