Need help...create disk image with my own contents

[Macadave]

Hi!

I recently bought a Mac Classic off eBay and have been porting games and software to it.

My current method is to run Mini vMac emulating 7.5.3 on my MacBook. I next follow these instructions from this forum to create a blank disk image:

http://www.emaculation.com/forum/viewto ... mac+floppy

I load that on the vMac, copy files to it (which I download from other sites like macintoshgarden.org), write out the image to a USB floppy (again with the above instructions and 'dd'), and finally load it on the actual Mac Classic.

So now I also want to copy some .JPG files over (for use in a HyperCard stack). But I'm not sure how to create my own disk image with my own set of files on it. Could anyone help me out with some instructions? It would be great if I could do that with the hardware and software I already have (MacBook, Mini vMac, USB floppy, 'dd' command).

Best,
Dave

Were do you get stuck, Dave?
You may put any files you want (including jpg) onto the blank image in MiniVMac that you intend to write with dd.
Sorry for the missing picts, btw - I thought Sharebin.net was a safe harbor for files those days.
Maybe I can figure out something over at Macintoshgarden.

On a side note, I would recommend setting up Basilisk II build 142 on an old PC with floppy drive any time.
If you add a ten bucks PCI SCSI host adapter to such PC, you may read/write various SCSI devices making file transfer to vintage Macs so much easier.

Mini vMac can read any image format. Also, Paul has an archive of image blanks on the Gryphel Project site that would help.

So, you can drop all your files into a DMG and mount that in Mini vMac, or use Paul's file transfer app inside Mini vMac to transfer them over. Use one of Paul's image blanks to make sure dd writes the correct format without image headers out to the floppy disk.

I guess what I don't understand is how to make the DMG on my MacBook (with my content), which I can then mount on the Mini vMac.

What is Paul's file xfer app, and how do I run it? If I could xfer files from my MacBook directly to the Mini vMac instance that would be ideal.

Which OSX version do you have on your MacBook? Disk Utility in current OSX versions will create HFS+ images that mini vMac cannot read and HFS images that mini vMac can read, cannot be written to in current OSX versions.

Try HFS Disk Maker. See: http://www.emaculation.com/forum/viewto ... f=1&t=8337
On your MacBook you create a folder with the needed files in. HFS Disk Maker can then create from that folder a HFS disk image that mini vMac can read.

http://www.gryphel.com/c/minivmac/extras/importfl/ is used to import files to the emulated OS from the host system;
http://www.gryphel.com/c/minivmac/extras/exportfl/ is used to export files to the host system from the emulated OS.

Note that resource forks don't get transferred by these, so you're going to want to use macbinary, binhex, stuffit or zip to flatten to a data fork only before transferring files that include multiple forks. JPEG is data-only, so won't be an issue.
