Need something checked on PC-FX mobo

[Charles MacDonald]

If somebody has the time and inclination, I need to get something checked inside the PC-FX.

On one of the two PCBs is a NEC uPD78C14 chip, near the center. It is a 64-pin rectangular QFP. Here's a link to the chip pin assignment:

Going counter-clockwise from the pin 1 indicator, I need to know how pins 21 (MODE1) and 23 (MODE0) are connected. One is probably connected to a nearby resistor or resistor array which may in turn be connected to +5V or ground. The other pin is probably directly connected to +5V or ground.

Also if you could let me know what all of the lines of text on the 78C14 chip are in their entirety that would help a lot.
Thanks!
