Zenith Z-183
At least one of the many onboard RAM chips is bad. I think I'm gonna track down another motherboard rather than trying to figure out where the bad one is on my board.
Otherwise, I know the display works and the system tries to POST. It's in decent condition, but yellowed like they all are. Hard disk is gonna be dead.
