3.1 ROM Installation Instructions
for Commodore Amiga A3000/A3000T

CAUTION: Before any internal expansion device is installed, the system 
must be turned off and disconnected from the power supply.  All cables

WARNING: Installation of ROM chips should be performed by an 
authorized Commodore-Amiga Service Center or by your Commodore-Amiga
dealer.  Neither Commodore nor Village Tronic will be responsible or
liable for any damages caused by improper installation of the ROM chips.
ROM chips are sensitive to static electricity.  Contact with a chip when
high levels of static electricity are present could damage the chip.  
Touching a nearby grounded metal surface, before touching the chip
can help reduce static levels.
