Upgrade 6.0.5 to 7.5.5 on my SE/30

The System 7 versions compatible with the SE/30:

7.0

7.0.1

7.1

7.1 Pro

7.5

7.5.1

7.5.3

7.5.5

Apple made 7.5.3 available for download as a full system (19 parts for the US version):

The individual segments were small enough to be transferred on 1.44 MB floppies.

7.5.5 was werely an update to 7.5.3:

System 7.1 was never a download from Apple, contrary to 7.0.1:

Exactly how to transfer and install a new system on an SE/30 depends on what you have to work with. Do you have access to another pre-1998 Macintosh computer (with a built-in floppy drive for 1.44 MB)? If so, does that computer have an Ethernet port? Do you have access to an older Windows PC (with a floppy drive)? A modern Mac or PC? An external SCSI CD-ROM drive? A SCSI Zip or other hard drive? StuffIt Expander 4.0.1?

Hej Thomas!

Yes, I am Swedish. Glad to be of help with a few suggestions regarding the SE/30 upgrade.

The nineteen files 7.5.3 system software version would require an existing boot disk with System 7.0.1 or higher. A Network Access Disk 7.5 can be used.

http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English -North_American/Macintosh/Utilities/Network_Access_Disk_7.5.txt

The idea is to place the nineteen files (once decoded) in a common folder on the SE/30 hard drive. Upon double-clicking the first (.smi) file, the entire disk image will be mounted. The Installer can be found inside the thus mounted image.

In this case, the first obstacle would be to make the Network Access disk. Could you possibly ask a friend with an approx. 1992-1997 Macintosh to help you? After a StuffIt Expander decoding of the .bin, Disk Copy 4.2 (the Make A Copy button) is used to create a floppy from the contained disk image.

Otherwise, it is possible to create the Network Access disk on an older Windows (95/98/XP) PC (with a floppy drive) via a disk-image program (such as WinImage), using a special technique. Could you perhaps locate someone with this hardware? If so, please post back for details.

Once a bootable Network Access floppy has been made, we can proceed with the system software installation.

How much RAM is installed right now? Hard disk drive size (MB)?

Hi Thomas,

To begin with, would it be correct to assume that all three are working (with an external monitor for the Quadra 700 and the LC)?

Could you have a quick look at (the equivalent to) "Om Macintosh..." under the Apple menu? Which operating system version is installed on each computer? How much RAM?

Do you have the external transceiver (such as Apple Ethernet Twisted-Pair Transceiver, Model M0437) for the AAUI-15 port of the Quadra?

I don't know if 7.5.5 is supported on your SE/30 but System 7.1 is lighter and uses less resources in CPU and ram.

I know your SE/30 is limited in hardware resources.

I use 7.1 on my Mac Performa 575 because it is a lighter OS that uses less resources.

You can email them and ask them what OS versions are supported on your Mac.

You can download from this website.

Hej igen!

Buying a second Macintosh computer is a good idea. If possible, try to get one with Ethernet. A CD-ROM drive can be used to receive transfers of downloaded files from a more modern computer (on a CD-R disc; burn at a low speed and keep any .bin or .hqx encoding intact until on the semi-old Mac).

Also, a pre-1998 Macintosh has a MiniDIN-8 printer port, which can be used for LocalTalk networking (in its simplest form, merely a plain MiniDIN-8M to MiniDIN-8M Mac serial printer cable).

4 MB of RAM is an absolute minimum requirement for System 7.5.3, but it is wise to install more. A 40 MB hard drive can hold an installed 7.5.3 system, but with very little space for applications, so a larger internal drive and/or an external SCSI hard drive (alternatively, a SCSI Zip 100 drive) would make things easier.

Often, vintage Mac parts can be best found via online auction sites.

OK.

Also, a normal Macintosh MiniDIN-8M to MiniDIN-8M printer cable could become quite useful (for LocalTalk-transfers between one of the three mentioned computers and the SE/30).

Another useful device may be an external USB floppy drive, for transfers on 1.44 MB floppies (formatted Mac or PC) from a more modern computer.

At least the Performa would be new enough to contain an appropriate operating system. There is no network card (the cover plate next to the modem; a card could be easily added). On the other hand, the machine has a built-in CD-ROM drive, so it would be possible to download files from the Internet using a more modern computer (Mac or PC), and then carry out a first transfer on CD-R to the Performa.

The LC appears to have a network card (thin Ethernet/thin coax/10Base-2) using a BNC connector.

Addendum

On the System 6.0.5 SE/30, do you already have some kind of communications program (terminal emulator with file transfer capabilities)?

Do you have an old external serial modem (could also be a PC-style model)?

Hej Thomas!

Yes, that machine would be OK for the purpose.

Check whether there is a web browser (probably an early version of Internet Explorer or Netscape) installed. RAM is limited, but you should be able to connect to plain http (not https) web sites for simple downloads. Also, is StuffIt Expander installed? With a transceiver attached to the AAUI-15 port, you could connect an RJ-45 cable to one of the LAN ports of a router. Set the control panel handling TCP/IP to use Ethernet and DHCP.
