1) A piece of tamper-proof tape, labeled "breaking this seal voids warranty". If you do major modifications to something, such as a TRS80 model 1, always put a fresh tamper-evident seal on it afterwards, to re-enable the warranty.

. . . and have him have to escalate it to somebody authorized to make exceptions, or argue with tandy lawyers?
Nah, it's more FUN to excuse the piggy-backed chips and extra circuitry added in with, "well, it's like building a boat in a bottle, and if the seal isn't broken, then the warraanty is still valid, even with modifications"
Although, for a while, we had a tech at the local Radio Shack "Computer Center", who would gladly ignore any modifications for which we gave him circuit diagrams. (lower case, extra keys, memory remapping, RCA jack for composite video out, reverse video, etc.)
