Rear view of the TV PCB board, showing the circuit layout. Note that pin 10 of the rightmost 74ACT574 has broken off the chip. Pin 10 is supposed to be lifted from the PCB, the trace leading to it cut, and a 1Kohm resistor soldered from pin 1 of the adjacent 74ACT574 to the right most 74ACT574.
Front view of the TV PCB board.


The part number for the 5x7 "red only" LED blocks is GMA8875C made by On Semi/Fairchild. The part is no longer manufactured and is obsolete.

An alternate part that Stern used and is labeled on the side of the block is LTP1557AC which is made by LiteOn. The datasheet for this LED block can be found here.

The resistor that appears to be a "hack" was a factory modification and is shown on the schematics.

The schematics for this board are identical to the Roller Coaster Tycoon schematics even though the RCT display panel orients the blocks rotated 90 degrees. The schematics can be found here.
