    Or they could have a tricky format that includes enough information that the Mac recognizes the disk as formatted but can't read the whole thing. That style of format was common in the PC world. I...

    The CIA published a list of tape drives used in the Eastern Bloc. Some use the exact same formats as IBM so just set to the matching IBM type and the tape should be readable. Some were just plain...

    If those are Mac high density disks, the LCIII should be able to read them. What does the 12kB file show? It might be a special format or if only a decade old might be in HFS+ format.

    Actually,...

    The 5MB and 10 MB SyQuest drives used approximately 4" platters. Makes them very distinctive in a collection.

    That report was late as the PDP-11 was winding up its market presence. Two other reports on bitsavers show the decline of the high end PDP-11; one describing superminis and the other 32-bit. The...

    Wikipedia doesn't source its claim of 600,000 or I would have looked at the source to see if it breaks down sales further. What I understand was roughly half of all PDP-11s sold as computers were...

    Gordon Bell's 1976 paper indicates more than 20,000 early PDP-11s made divided between a bunch of models. The most common version would have to be the PDP-11/03. The book Digital at Work has some...

    There was libhoudini which would run Android ARM apps on top of X86 Android. Not sure where to find it now. It was less than stable and quite slow so it may not be the solution you hoped for....

    I would like more pictures. British repackaging of early DEC hardware? Guessing that from the use of "disc" on the label. Seems likely to have an interesting story behind it.
