Intalling MacOS 7.5.3 on Macintosh LC II

[Papalapa]

After hours of work completely dissasembling, cleaning, restoring keyboard tracks with permanent pencil, replacing some on-board capacitors, replacing the ejection mechanism of the floppy drive, replacing the ball of the mouse and installing a Farallon network card now I'm proud to own a working Macintosh LC II

I installed the MacOS 7.5 using floppies but now I want to upgrade to 7.5.3 and I can't do that. The MacOS 7.5.3 is a file image of 43MB file and I have no way to copy this image to the Macintosh LCII. Although it has a network card I was not able to connect to the router of my home network at the moment (this will be another post) and the only communcation way that it has with the external world is the 1.44MB floppy. I know that 7.5.3 is intended to install as an "upgrade", has not boot diskette and needs to have an MacOS already installed in the computer so, there's no way to install it using a floppy set as 7.5.

Anyone knows how can I install MacOS 7.5.3 on my 80MB hard disk, 10MB RAM Macintosh LCII?

Thank you!

First of all...congrats on what sounds like quite an involved project to resurrect this old LC II. Nice job!

Two thoughts:

1. Originally for your LC II...7.5.3 very likely was distributed on floppy disks. Thus a 1992 LC II with an origonal 40, 80, or 160 meg HD really wasn't designed to work with such a large disk image. I'm willing to bet that this 43 meg disk image more than likely contains 19 individual 1.4 meg floppy disk images that could be used to create 19 individual 1.4 meg floppy disk install disks. Now if you had a large enough hard drive (internal or external)...you may be able to work with this 43meg image directly. Otherwise you cuould create 19 individual floppies. Yes a pain in the butt for sure (and you need to find 19 floppy disks that actually work)...and this assumes that the floppy drive in this computer is still functional.

2. 43 megs for this 7.5.3 file image of Classic MacOS 7.5.3 sounds pretty large. If you see the link below...someone posted that 7.5.3 was originally distributed on (19) 1.4meg floppy disks. Do the math (19 x 1.44 = 27.36 meg).

+1!!

I just came across this this evening and it sure takes me back to those days but I'll have to think about it and see if I can come up with some suggestions and post them tomorrow.

As Nick mentioned, and as I recall, such an image when expanded would display all the disk names with their number to do the install. The question now if I understand things correctly, is how to get the image installed on to the drive and get it expanded.

I'll have to sleep on it but maybe someone will come up with the proper answer before hand.

Back in my LC days, the maximum OS was 7.0.1, and 7.0 came with some two dozen white floppy disks, and the update to 7.0.1 came on an additional ten or so. Again, from memory, OS7.5, and the more popular 7.6.1 fur use on the 'net, the machine required a CD installer.

Maximmum OS for Macintosh LCII is 7.6.1 and actually I installed MacOS 7.5 that comes in only 7 floppy disks (Spanish version). After doing some tests this weekend I thinck that I'll downgrade to 7.1 in order to gain some speed. Anyway, the original problem remains: how to copy files bigger than 1.44MB. To install Open Transport 1.3 for example, I copied the uncompressed files that I have on the Basilik II emulator and fullfiling the floppies up to 1.44MB but not always is possible to do this due files more than 1.44MB are present.

To install Open Transport 1.3 for example,

The bigger problem I see with that is that Open Transport 1.3 seems to be meant to work with system 8.1:

Technical Q&A NW64
Open Transport Versions
Open Transport Versions


Other than that, where are the other large files stored and do you have any filesharing enabled???

Thanks a lot for the information, I'll try with Open Transport 1.1 instead of 1.3. Actually I'm trying to install MacOs 7.1 but it seems that I have an upgrade, not a full version set of floppies so, I'll look for the full set of disks in Spanish and install Open Transport 1.1 later.

The files are not really big, it depens of the program but Netscape 2.0 for example is about 3MB (more than 1.44MB), Freehand also bigger. In fact, all of them are files of the programas that I'd like to install on the Mac. The files are actuallly on the PC but I also have a pendrive connected to the router and shared with all the home network.

I came across the following software you may be able to use, but you may already have access to it:
Vintage Mac Software Library
MacFixer Vintage Software Library

Various install options seem to be available.
No sign of a separate Spanish Version that I could see if it was even available.

Thanks a lot, is a very useful link. After some tests I realized that the best option for me is MacOS 7.5 with a custom installation that doesn't install some elements like Quicktime, Desktop backgrunds and so on.
