RAM upgrade for Macintosh SE30

[surfer150]

I’m looking for upgrading my SE30 from 4 to 32 MB of RAM. But I’m uncertain which type of RAM i need. There seem to be to types of 30pin SIMM modules: FPM and EDO.

I found this modules, will they work?

Does the SE30 support parity?

Those should work just fine. The SE and SE/30 aren't very picky about what type of RAM you get and parity doesn't matter.

Thank you very much. I ordered this modules now.

The RAM arrived and I upgraded it today. Additionally I put in a new HDD with 4 GB and a ROM-Inator II in order to be able to address the entire RAM without MODE32.

But I’m not able to install Mac OS 7.5.3. Even though it should support up to 4 GB partition size, the installation does not work. It says that 29619 KB are needed, but -35371 KB are available. What can i do? I already initialized it with patched HD SC Setup 7.3.5.

My Classic II has a 4 GB drive too using the entire drive as a single partition was not an issue at all.

On your 4GB drive, partition to < 2.0 GB x 2, this is a limitation of the file system

But why it works on my Classic II with 7.6 then?

On System versions before 7.5, try to avoid handling volumes that are larger than 2GiB (2,097,152KiB, 2048MiB) because HFS in these versions cannot address more than 2GiB volumes. 7.5 has support for 4GiB volumes, and 7.5.2 (which was mostly for PowerPC machines, most people won't see it) supports up to 2TiB.

Because you’re trying to install while booted to System 7.1 and it always thinks the partition is full if larger than 2GB. You should start up from System 7.5 or later to do this install.
