Delphi electronics says these are 1k x 1k sram (memory) chips manufactured by National Semi a long time ago as stated above by OH. Without a schematic it can be difficult to TS a PCB. If the fuse takes a while to blow you might try touching carefully around the board components to see if one burns your finger or maybe use a Ir camera to locate where the power is going. Be careful since there can be high voltages if this board also has the power transistors for driveing the High Voltage Xformer on it. Another trick I'v used is to replace the Fuse with a large resistor and disconnect Parts (IC's and such) one at a time and note when normal circuit voltage returns since it will most likely be very low with the bad component installed.
Good Luck -elf
