Help getting MacOS 7.6 on SE/30

[mloret]

Hey guys. I am trying to get OS 7.6 on my SE/30 following the installation of my Rominator II. I am using the instructions found here from the nice folks at BMOW.

I am stuck on the step that says to modify a 7.0.1 Disk Tools floppy by copying a couple of extensions into the extensions folder. There are no folders on the Disk Tools floppy. What am I missing here?

The "System Folder" is a folder.

The Extensions folder is in there.

 

[mloret]

Yes, but inside the system folder there is no extension folder.

That’s not a 7.0.1 disk tools floppy. That looks like some flavor of System 6.

Looks like you were right. I guess the folders on my floppy emu are wrong. I downloaded 7.0.1 floppies but now it's telling me that I can't modify the disk because it is locked. How do I unlock it? I tried making another copy of it, but the copy of the mounted disk is locked as well. I tried "Get Info" and didn't see an option to unlock. Any ideas?

Are you using mini vMac? This old thread may help. https://www.emaculation.com/forum/viewtopic.php?t=9935

Well I stuck to the adage if at first you don’t succeed, try, try, try, try, try again.

I found the directions to be crap so I utilized a combination of Sheepshaver, MinivMac, Apple Legacy Recovery image and two BlueSCSIs to turn my SE/30 into a triple boot currently running 7.6.1. Unfortunately it’s very slow. I might dial back to 7.5.5.

one thing that might speed it up is getting one of bolle's micromac 040 accelerators, if he still sells them

Thank you! Yes it’s on my never ending wish list

Also, disable Virtual Memory. It appears to be enabled in your screenshot, which likely would drain performance out.

 

[mloret]

Okay thank you for the tip! I will do that!

I have the same setup. I used my IIsi to install 7.6.1 then transferred my hard drive (blueSCSI) to my SE/30. Booted to the ram disk which is 7.0.1 then used resedit to change the system setting and rebooted and everything worked. Its simple if you have a IIsi hanging around. I have two.

 

[mloret]

I used Sheepshaver and my BlueSCSI's. Sheepshaver was probably used in the same way you used your IIsi.

6.0.8 or 7.1 is the way to go on an SE/30 IMO. I would only consider 7.5/7.6/8.0/8.1 if you have a 68040 in there.

 

[Crutch]

You don’t need an 040 (7.5.5 absolutely flies with a 50MHz Diimo 030) but I would recommend an accelerator of some kind to run 7.5.5 in an SE/30, yes.

 

[joshc]

True, but an 040 makes it fly even more.

 

[Phipli]

True, but an 040 makes it fly even more.

You'll be shocked to know I don't own an 040 PDS upgrade!

I have a 50mhz 030 and a 66mhz 601. The 50mhz powercache gets moved between machines. It's not much different to a 25mhz 040. Upgrades are expensive.

My dad has three 040 pds upgrades and no 030s. He clearly is more of a speed deamon than me.

Your Mac SE/30 has only 16 MBs Memory.
I think the point of installing a clean ROM inside a Mac SE/30 is to enable more memory, not necessarily to then advance the operating system to the highest version it will take with only 16 MBs. There are many extensions installed in Mac OS 7.6 thru 8.1 that you most likely will not need with could be removed. Mac SE/30 with 7.1 OpenTransport, and 64 MB memory is far faster than Mac OS 7.6.1 bloated. The advantage with at least Mac OS 8.1 is that it support hfs+ but is't not very speedy even with a descent amount of RAM.

24bit addressing only allows 8MB of RAM.

I didn't mention 24 bit addressing.
