This Technical Reference Manual is written for owners of the TRS80 Color Computer, who have a thorough understanding of electronics and computer circuitry. It is not written to the beginners level of comprehension.
Radio Shack will not be liable for any damage caused, or alleged to be caused, by the customer or any other person using this technical manual to repair, modify, or alter the TRS80 Color Computer in any manner.
Many parts of the computer electronics are very sensitive and can be easily damaged by improper servicing. We strongly suggest that for proper servicing, the computer be returned to Radio Shack.
Because of the sensitivity of computer equipment, and the potential problems which can result from improper servicing, the following limitations apply to services offered by Radio Shack:
1. If any of the warranty seals on any Radio Shack computer product are broken, Radio Shack reserves the right to refuse to service the equipment or to void any remaining warranty on the equipment.
2. If any Radio Shack computer equipment has been modified so that it is not within manufacturers specifications, including, but not limited to, the installation of any non-Radio Shack parts, components, or replace-ment boards, then Radio Shack reserves the right to refuse to service the equipment, void any remaining warranty, remove and replace any non-Radio Shack part found in the equipment, and perform whatever modifications are necessary to return the equipment to original factory specifications.
3. The cost for the labor and parts required to return the Radio Shack computer equipment to its original specifications will be charged to the customer in addition to the normal repair charges.
