Apple IIGS: System Software after 4.0 Requires 512K RAM



I have a 256K Apple IIGS. What's the latest Apple IIGS system software
version for a 256K Apple IIGS without a memory expansion card?

When I try to load System 4.0 through 5.0.2, I get a "RAM Disk Too Large"
error message. When I go into the Control Panel, RAM disk is set to 0K,
84K RAM in use, and 171K free. Why is this?

Apple IIGS system software after version 4.x requires at least 512K of RAM.
Without at least this much you'll be limited to version 3.x or earlier of
system software.

We strongly suggest that you upgrade to at least 512K of memory, even if
you're only going to use the earlier system software.
