When repairing boards and using donors it is important to note you cannot just swap ASICs between Lynx II consoles, they are not all the same.

Below is a list of known supported chip swaps:

As you can see it seems like so long as the main text is not VLSI (an EPYX chip) going to an Atari branded chip you are ok.

Anything not in this list I have personally not swapped so cannot guarantee.
