Another reason to not love these machines: If SIMM 0 has failed, the firmware reports a failure in SIMM 0. If SIMM 1 has failed, the firmware reports a failure in SIMM 1. If SIMM 2 has failed, the firmware reports a failure in SIMM 3. If SIMM 3 has failed, the firmware reports a failure in SIMM 3. > > Even knowing that, I’m not sure I want to > invest hundreds in new RAM for a machine whose b-cache is known to be a > ticking time bomb.
