  1. Those technically weren't arrow keys, and instead Apple called them "field motion keys." They work in Microsoft Multiplan and probably other spreadsheet applications. See Inside Macintosh, volume 1, page I-36. By the way, the Macintosh can tell whether a keypress came from the main keyboard or from the keypad, even if it's a key which is common to both.

    About lubricating that floppy drive...

    It prevents dust and other particles from falling into the drive.

    New member buys a macintosh se/30

    Leave the Mac on for about 4 or 5 hours and the sound should be louder. It's a failing capacitor problem, as many others here have said.
  4. Correct. The arrow keys and some of the other keys which the Plus keyboard added are dependent on System file support. As long as you're using System file version 3.0 or later (1986), you should be fine. You can also copy the appropriate INIT resources from a newer System file into an older System file, if need be.
  5. The MacBinary format does not have a CRC checksum. This explanation does not make sense. Do you not keep both data and resource fork in RAM? MacBinary is 3 parts: 128-byte header, followed by data fork, followed by resource fork. Surely writing these 3 parts in one combined operation is no worse than writing 2 separate files to disk. You're not reducing the size of data written to disk by using AppleDouble instead of MacBinary.
  6. I recommend using MacBinary format instead of AppleDouble, especially if you want to facilitate easy transfer to vintage Macintosh computers. Also, every version of OS X so far released under HFS, HFS+ and APFS supports resource forks. Consider using native filesystem support under OS X for writing resource + data forks into a single file.
  7. There were two versions of this brochure. One was larger and printed on heavier paper, and it's the one that the OP has. A slightly smaller one with a slightly different layout was inserted in several leading news magazines, including Business Week and Newsweek. Both have the same content. I have a copy of both these versions.

    Error while Initialising Floppy Disk (Macintosh SE/30)

    No, I mean the brown part that comes in contact with the disk drive's read/write heads. Just paint a single stripe of isopropyl alcohol on the top and bottom sides, and this will function reasonably well as a cleaning disk.

    Error while Initialising Floppy Disk (Macintosh SE/30)

    By the way, you can make any disk a cleaning disk. Take a disk that you don't value so much and use the cotton swab to brush on some isopropyl alcohol on both sides of the magnetic media. Just a single brush stroke per side with a saturated cotton tip will do.

    AppleTalk net cable

    With PhoneNet wiring? Check your phone line to ensure it has all 4 conductors, and not just 2.

    AppleTalk net cable

    For 2 computers, you can use an Apple StyleWriter cable to connect. Only advantage to using PhoneNet for 2 computers is if you need to span many feet with your cable. (So far I'm repeating what olePigeon already said) When using RJ-11 cabling for PhoneNet you need to check carefully and ensure that your modular phone line has all 4 conductors. Cheaper lines will only have the red and green conductors. PhoneNet doesn't use these; it uses the black and yellow conductors.

    .dsk raw floppy format?

    I run Mac OS X 10.5 with MFS Lives! filesystem kernel extension so I can mount MFS and HFS disks using DiskImageMounter. MFS is read-only with this OS X kernel fs extension, so I use mini vMac if I need to modify MFS disk images. I don't "write out" disk images to physical floppy disks. Small files get XMODEM transferred via a serial line from the Mac OS X machine directly to the vintage Mac. Large files get put on a Zip disk for sneaker-net transfer.
  13. CDEVs came with the new modular Control Panel in System 4.1, which debuted in March 1987 with the Macintosh II.
  14. That's the reason why I gave up on vintage Macs with internal hard drives and switched to Apple II exclusively for many years. Now I'm back to pre-SE, floppy-driven Macs. Failing or lack of hard drives ranks right up there with failing capacitors as the most annoying aspect of vintage Macintosh computing.
  15. Is it possible to do this if the disks are not ProDOS formatted? Maybe, but it's a lot trickier. DOS 3.3 was designed only to use the 5.25" disk. There are a few work-arounds, such as the one that waynestewart mentioned above.
