>> so TAVA identifies the non-compliant chip, let say it's a Z80, then what? Do they just replace it with another chip, let say a M68332 or a Intel 8051, then what? Do they unsolder the Z80 from the circuit board and replace it with a 68332 or a 8051? << Mike the (Zilog) Z80 is a MicroProcessor. The (Intel) 8051 is a MicroController. The MicroProcessor (MPU) does not contain internal ROM so it would not (by itself) be a date sensitive component. The MicroController does contain internal ROM so it would have to be evaluated. Of course you could not swap any MCU for another. A new component, with the identical electrical characteristics (speed rating, revision, package type etc.) as the one being replaced, would have to be re-programmed (with date compliant code) from source. Of course memory availability (cell locations) may be a constraint.
