.Ndif, Disk Copy, Basilisk II, Mac OS 7.6 and headaches.

OK, I've gotten Basilisk II up and running Mac OS 7.5.5 but I wanted to upgrade to 7.6.1. I dug up a copy of 7.6 off of the pirate bay and have been trying to get it running, but so far I'm getting nowhere. The author of the torrent claims its in .ndif format but I can't get Disk Copy to read it (genius wants everyone to use a newer mac to burn it to CD and then run it on their old system). DC 6.5b13 wont run and DC 6.3.3 says its not a recognized file type (and crashes Basilisk II half the time when I try to load it). I don't know of any windows program that can mount this file type either, not do I know how to convert it into a more standard file type. Anyone know how I can pull this off or get a copy of 7.6 that wasn't put together by a moron?

Probably you may like Mac OS 7.6 over 7.5.5 for some good reason ( I don't know the diference)
I use Mac OS 7.5.5 as well and System 8.1, so... why don't you use System 8.1 instead?

if you need a copy of System 8.1, I might be able to help

Mac OS 7.6 is somewhat more stable and faster than 7.5.5. I have ALL the images for the different system software but haven't gotten around to it yet.

Try mounting your .NDIF file using Stuffit Expander 5.5. ( file ---> preferences ---> Disk Images).

Sadly, Stuffit doesn't do anything with it (simple drag and drop does nothing) and I can't install ShrinkWrap because it requires a registration number. Any other ideas?

You could also try ShrinkWrap for mounting all sorts of disk image types under Classic. It´s not as 'picky' as Disk Copy…

Doh, of course the number was in the image. So I got ShrinkWrap going but it also can't read the image. So, as I said before, I think the guy that made it rides around in a short bus. Does anyone know where you can find a mountable image of 7.6 that can be booted and installed on a 68k based Mac without having to do anything stupid like muck around in OS X or burn it to a CD?

Was the Mac OS 7.6 NDIF disk image compressed in any way when you downloaded it ?
Or did you download it as a .img / .image ? Is so, it's hosed.

I checked out the download you are talking about (probably) on TPB. It is hosed. It can't work for anyone. Here's the problem, as quoted on the TPB page:

"I cannot get this to work, no matter what application I use to expand the tbz (StuffIt Expander 7 Classic, OS X's tar, OS X's Archive Utility), the resource forks of the files are gone, meaning the files are useless. I can't mount the 6CD with Disk Copy 6.5 either because of the missing resource fork."

NDIF files are not good for emulation, since they rely on resource fork data, thus get hosed if they are ever exposed to Windows. I think that the guy who made the torrent created the archive in Windows, because even when I expanded the archive inside of the emulator, it wouldn't mount.

Most other disk images created by Disk Copy can be exposed to Windows and mounted just fine, since they don't rely on the resource fork.

When I used Shrinkwrap to "verify" the image, it said:

Target: bigdisk:The Files:AppleMacOS76CD
- Volume Name: AppleMacOS76CD
- Volume Size: 159028K
- File System: MS-DOS
- Compression: None (r/w)
- Encryption: None
- Savings: 0%
- Calculated CRC-32: $07E2B083
- Speed: 26990744 bytes/sec

I think that the "MS-DOS" file type is a sign that I was correct when I suggested that the resource fork data was wrecked by Windows even before the archive was created in the first place.

The updates in the archive don't mount either.

Ok, got a 7.6 CD-ROM image which I can get Basilisk to boot from. Converted it from a compressed NDIF image to NDIF read-only in OS X. I´m zipping it and upping it to where?

I made presumtive decision you´re more interested in OS 7.6 in English rather than Swedish, right?

Mediafire.com is a decent place and you don't need to sign up to do it. If you can't get that to work theres the usual suspects: rapidshare, or bittorrent if you want to bother seeding for awhile. Thank you for the help, no one seems to care about 7.6 since 7.5 is free and .6 isn't.

And yes, English would be more useful than Swedish }:-)

As I said, I have the image (CD ROM and floppy images), but I can't get them up right now. They'd easily fit here, though.

@Balrog: is it OK to put a copy of 7.6 here as the CD-ROM contains the floppies, as images, too?
@lando242: I´m upping it to Deposit Files: that´s ok?

I have a Disk Copy image of the 7.6.1 universal install CD (I have the actual disc) but I didn't want to upload it because to my knowledge Apple never released it for free like Mac OS 7.5.

It's just as much abandonware as all the other stuff we have here. (Remember when Steve Jobs did the funeral for OS 9?)

7.6.1 would be fine.

Note that these DO NOT work on the PowerBook 3400; that machine requires a special version of 7.6 (which I also have).

I just posted to TPB the "Apple Legacy Software Recovery CD" that boots into Mac OS 7.6.1 and includes installers for every Mac OS from System 1.0 through Mac OS 8.1 as well as a bunch of other stuff.

I've tested it on actual Mac hardware as well as emulators. It boots correctly and all of the installers seem to work.

The zipped .iso weighs in at 577.8MB so I think it's too large to post on this site.

Here's a link to the torrent on TPB:

SwedeBear I download the file and moved the .zip into Basilisk II and used StuffIt to unzip it, up to that point everything works good. I now have to files: Apple Mac OS 7.6 CD.image and _Apple Mac OS 7.6 CD.image, neither mounts in ShrinkWrap or StuffIt. What do I have to do to make it work inside OS 7.5.5?

Lando,

You probably cannot open those images in the emulation. ZIP files made in OS X like the one you downloaded cannot be properly expanded in Mac OS 7. We have the same problem with a number of games that have been uploaded to the site in ZIP form.

Maybe try the other torrent link provided.

Sometimes Disk Copy created read-only ndif images are not helpful for emulation, since they rely on the resource fork to be mounted. Read-write images are more flexible, and can probably be mounted in Basilisk II on the host (be that Windows or Linux or whatever)!

I can fix zip files made in OS X. Just point them out to me!

EDIT: Always use read only images! Prevents data loss as they're checksummed.

Lando,

I tried Swedebear's image myself. It should work for you. Unzip in Windows (not Mac OS) and then mount it along with your hard disk images in the GUI. You can then install!

@lando242: I have bad experiences of letting StuffIt decompress .zip archives from unknown application and system. I myself use BetterZip in OS X, as in this case, or under classic system, ZipIt when I have to use .zip.

watchsmart: For some reason that didn't work. I add it to the volumes list in BasiliskIIGUI.exe and when I start emulation I get a message from OS 7 that the disc isn't readable and it wants me to initialize it. It does this for both files.

In other news I did get the legacy recovery CD going in Basilisk II, sometimes. I mounted it in windows with Daemon Tools and then used Basilisk's CD ability to pass it to the mac. For some reason this only works some of the time: boot up one time and the CD is there, boot up the next and its gone. I got it working once and installed OS 7.6, when finished it said I needed to reboot, without even closing Basilisk I restarted and the CD was gone. Unmounting and mounting the image in Daemon seems to fix this, why, I have no clue. Doing the same while Basilisk is running and you get an unreadable disc warning.

Anyway, I got everything upgraded to 7.6.1, thanks everyone for you're help and your files. I'll seed the torrent for at least the next few days.

Lando: As I mentioned, the first CD image works fine for me. I will fiddle about and see what configuration on your end could cause that.

As for the second CD... you don't need to use Daemon tools. Well, I guess you don't need to fix the first image! For future reference, keep in mind that you DO NOT need to use Daemon tools. You can just type in the full path of the CD image in the Basilisk II GUI "CD-ROM" drive box (where you would usually just have the letter of your CD-ROM drive). In this case, you might also want to make the cd image "read only" in Windows. Doing it that way can be a bit more stable.

watchsmart: Sorry, I neglected to mention that trying to mount the image in BII causes it to crash every time. BII doesn't seem all that stable on my system, I have run into several ways to reproducibly crash it or cause it to lock up. I guess it just doesn't like me cause all my other emulators, games and programs work great. I've had the system for over for years and everything up to date driver wise so its not an instability issue with the hardware. Does BII not like Hyperthreading (Intel P4) CPUs? I have heard that some programs can have issues with it.

I'm not really sure. That might be the case.

If you aren't already using an unofficial version, you can find some over in this thread:

http://www.emaculation.com/forum/viewtopic.php?t=5282

Try out that July build for increased stability over the version on the official Basilisk II site. The August build is only for the "black screen" problem reported in another thread.

Glad to hear you have these. Would you care to share?

My understanding is there were four in this series - I haven't been able to find anyone with any of the other three.

Does anybody have download links for verified "good" CD images of Mac OS 76, 7.6.1, and the Apple Software Recovery discs? The links posted in all the other comments here are long dead.
