RamDisk+ Crashing
Posted by: IlikeTech on 2016-12-28 10:05:08
Hello, I am trying to load Mac OS 6 into ram using the RamDisk+, however it crashes with a coprocessor not installed error.

Why?

Thanks

Does RamDisk+ require an FPU unit?

If the Mac in question has a 68000 or 68020, perhaps the message is referring to a lack of PMMU.

It was running on a Macintosh Plus. I'm not sure why, but it got partly through Loading files before crashing.

Sounds like you may just have a corrupt copy of it. Try a fresh one.

I have used this on countless Pluses and other non-coprocessor Macs with no problem.

Um, I don't currently have a way to do that. I can't load a fresh copy because I got the disks from Reasons. I'll let you know when I can.

How much RAM do you have installed in the Plus?  If it is the stock 1mb, you may be a bit cramped for that space sharing between RAM and disk.

4mb of 3chip Simms at 7ns were installed.

Oh good 🙂 you should have adequate space for both actual usage of the RAM as RAM, and some allocated as a disk.

Yea, my ram was shot, so I figured why not upgrade anyway.
