@ -48,9 +48,12 @@ DIPSW are present on the main board (instead of on the filter board) and the
SOIC8 chip (a secured PIC?) is not populated (the solder pads are there though).
There's an extra sound IC AN7395S (it's not populated on Hornet).
The PALs/PLDs are the same on NWK-TR and Hornet.
Both Racing JAM/Chapter 2 and Thrill Drive use two video boards.
The top video board is set to MASTER/TWIN, lower video board is set to SLAVE
They are otherwise identical.

Notes:
CN1 - Connector joining to CPU board CN4
CN2/3 - RCA jacks for network cable
2G - Small SOIC8 chip with number 0038323 at location 2G. An identical chip is present on
*some* Hornet games on the GN715 CPU board at location 30C. It may be a PIC or EEPROM.
On Hornet, the chip seems to refresh the data in the Timekeeper RAM when the battery
dies and keeps the game working. It's purpose on the network board is unknown but it may
'upgrade' the data in the NVRAM to the network version of the game for a twin cabinet set-up.
