For System 7.0 - 7.6
This app works with: Basilisk II,

The Apple Macintosh Quadra 630 features a 33 MHz 68040 processor, 4 MB of RAM, and a 250 MB hard drive in a compact desktop case. An internal 2X CD-ROM drive and video input/output also were available as options. Notably, the Quadra 630 additionally was the first Mac to use an internal IDE bus, rather than SCSI, and as a result, it supported cheaper hard drives than earlier models.

The Apple Macintosh LC 630 (PC) features a 33 MHz 68LC040 processor, 4 MB or 8 MB of RAM, either a 250 MB or 350 MB hard drive, and a 2X CD-ROM drive in a compact desktop case.

The Apple Macintosh Performa 636CD features a 33 MHz 68LC040 processor, 8 MB of RAM, and a 500 MB hard drive in a compact desktop case. The Performa 636CD is identical to the Performa 635CD, but the 636CD shipped with more RAM and a larger hard drive but without a 15" Apple color monitor. The educational version of this model is the LC 630 and the business version is the Quadra 630.


This is Mac OS 7.1.2 for the Macintosh LC 630 and Quadra 630. This is the exclusive system software release for LC 630 released in 1994, with the revised Memory control panel.

Please note that the above CD image was modified and corrected to save download time as the original CD dump had become a bloated 500MB after compression, even tho' it only contained 50MB data inside. Also, the original CD dump had issues, some virtual mounters identified this as corrupt, however it did burn OK.

MD5sum checksum: ad62b6036361339c12149e5bb1120fa7 *
Note: Zip archive (23.5 MB) contains ".iso" image file of install CD for SSW 7.1.2

See also Mac OS 7.1.x page for more Mac OS 7.1.x disk images, machine-specific installers, and CD-ROM images.

Architecture: 68k

To get it work in Basilisk II, install System Update 3.0 (make sure it's 68020). May work for other Performa 630 series.

Good job, please include the CD scan. I know this CD has PCI Expansion Info inside Extras folder, can you upload it into parts?

OK, but a "please" would have been nice. I will do it on the weekend. Mine is CD Version 2

Gimme the PowerMac 7x00 CD image, upload it and include the CD scan. I do not accept CD version 3.0, that's I already have.

Apart from the two system disks that I have already uploaded, I only have a Power Mac CD 7.5.3 for 7200,7500,7600,8500,9500 series and the G4 disks that you have already asked about. All other system install CDs that I have are too recent to be of relevance here.

mrdav, do you have any other CDs than Quadra 630 system discs?

@mrdav: Thank you for checking the original media thoroughly. It looks like it is developing problems like many CDs will do over time. So its just as well that we have it backed up (it must be the rarest of the 630 install sets).

MikeTomTom, thanks for modifying the upload. I have now had time to check out the problem. I believe that the problem is with the original media. I have tried imaging the CD with a later version of toast, also made a cdr with Disk Utility, and tried compressing both with zip just to be different, but the file remains stubbornly bloated. I also tried mounting the different images as iso under windows but the virtual disk software just gives an error message about a possible corrupted image. Anyway, we now have the best outcome. We not only have an exact image of the disk as it was distributed (historical value), but we also have a version without the excess free space (practical convenience).

Plus T/Maker's ClickArt Selection & the game Spectre Challenger & Mavis Beacon 2.0 Smile

Yes, my upload had to be modified to correct the issues with the original upload. No matter, its a good one if all you want to do is install this version of the OS (its bootable on suitable hardware too) and all of the files are intact & complete. Plus only a 23 MB DL.

Of the original upload, I cannot detect any other data to explain the large file size. There is a corruption with what was archived here, so perhaps either the original media has a problem, or Toast failed to copy the disc correctly, or DropStuff made an error when compressing. Only mrdav will be able determine this, when he has the time to.

Thanks for the first draft Mike (seem that Desktop DF/DB are modified and this will not added to my archive until mrdav uploads it again). So why the disc is bloated 500MB because of audio partition on CD?

Oh one more thing, this CD has some applications bundled inside such as At Ease & Clarisworks. Neat!

@mrdav: Thanks, I've placed up what I got. The problem (I think) is that there is a checksum error in what you archived originally. Its only a very tiny non-fatal error, but it prevented me from mounting the image in the virtual CD/DVD image mounter and it also prevented me from mounting the image in Toast Titanium (Fatal. Needed to reboot on that one). However Toast did allow me to burn the image to a CD OK - The verification of that burnt CD also failed (same error as when attempting to mount the image file), but I can still access and mount the burned CD in the Finder.

[Edit] I ended up junking my original efforts to compress the 500+MB original upload as the checksum errors wouldn't go away and Stuffit was making a mess of it... I rebuilt the CD using the original data section minus the 500+MBs of empty space. I've ended up with a clean copy of the Install CD that is error free and the .iso burns to CD resulting in zero errors, so that is all good. However its no longer an original copy. Now a 23.5 MB download, so thats not so bad.

The virtual CD/DVD image mounter also mounts this .iso OK, if you don't want to burn to CD.

MikeTomTom: I just used dropstuff as I always do for CDs. Don't know what happened there. Feel free to reupload as necessary.

My posts here will be intermittent for a few days. I am in Tasmania and out of communication for a couple of days

Good, upload the smallest one and check the difference.

Interesting that the image is so large. There is only approx. 40MB of data and 500+ free - I can't detect any more than that. Excellent content tho'.

I'd have thought this would compress a lot more and down to a size suitable for arching here, too.

[Edit] yes, I was able to (Stuffit) compress the Toast image to 27MB. Mrdav did you have compression turned off in your Stuffit prog?

Thanks for that shining CD image. However why this CD is bloated 500MB+? Is anything extras around here?

A Quadra 630 was the second Mac I owned. I inhireted it with a Super Mac from when my dad's business shut down. I liked the Quadra better. It fit on my desk better.

Ah the memories.

Living in the anti-antipodes (Sweden) I can only confirm mrdav's experience. I´ll up it somewhere else, though, just in case… Wink
