Apple IIGS Rev. 1 (aug 15, 1987 – dec 1, 1992)
Description:
In August 1987, Apple released an updated ROM that was included in all new machines and was made available as a free upgrade to all existing owners. The main feature of the new ROM was the presence of the System 2.x toolsets and several bug fixes. The upgrade was vital, as software developers, including Apple, ceased support of the original ROM upon its release (most native Apple IIGS software written from late-1987 onwards would not run unless a ROM 01 or higher was present, and this included the GS/OS operating system). This update also allows up to 8 MB for the RAM Disk, added some new features for programmers, and reported the ROM version and copyright information on the startup splash screen.
