A software package called Space Quest, part of the Endless Disk Drive, can
produce a Fatal System Error -> 0814 unless the following rules are observed:
- An Apple IIGS with serial number E704 or less needs to have both the VGC
and ROM upgrades.
- An Apple IIGS with serial numbers E704 - E723 needs the ROM upgrade only.
- You must use System 2.0 or later. This means that Space Quest will not run
with the old Apple IIGS ROMs (342-0077-A).
