I have an LC III running System 7.5.5 with 36 MB of RAM and the system software is using up ~80% of the RAM (30,699K, see first picture below). I'm running it off of a ZuluSCSI. However, when I boot off a disk image that uses 7.6.1, the system software uses only 2,640K of the RAM.
With the 7.5.5 disk image I have tried booting with the shift key held down, to disable extensions. I have also tried to zap the PRAM (Cmd-Opt-P-R at startup, cycle twice) and I tried rebuilding the desktop on the disk (Cmd-Opt at startup). None of this changed anything.
I also tried a different disk image with 7.5.5 and I see the same usage of ~80% of the RAM by the system software. Is there some known issue with System 7.5.5 and the LC III? Any ideas are welcome!
