The hardware manual covers OCS chipset. All the other RKMs cover AmigaOS 1.0 & 1.1, except the includes and autodocs, which is up to AmigaOS 1.2 & 1.3.
I have the Intuition one. R.J. Mical wrote it and there are some interesting concepts mentioned in it that didn't seem to make it to the finished product, such as standard screens other than Workbench, I guess for consistent environments.
