Arithmetic Logic Unit (AM2901). There are four of them on the Aux board.
They handle much of the mathematics that create the 3-D space of the game.

"T" indicates a timeout error, which means that the two boards aren't
talking to each other properly (i.e. the Aux board doesn't place data on the
inter-board bus when it is supposed to). "L" and "H" mean that the Aux
board is placing data on the bus, but it's not the *correct* response that
the self-test was expecting.
