Gates the 68k data bus to the memory card slot and palette RAM. Only found in AES systems ?

PROG B22 (AES cart ROMOE ?) = ROMOEU AND ROMOEL like in NEO-E0 ?

PALWE = PAL OR R/W.

Pinout

OpenOffice Draw file: File:Neo-g0.odg

D0~D15: 68k data bus
PALD0~PALD7: lower byte of palette data
PAUD0~PAUD7: upper byte of palette data
MCD0~MCD15: memory card data bus
(51) is "enable MCD0~MCD15" pin
(39) is "enable PALD0~PALD15" pin (confirmed on MV-2F chip used as ADPCM-A multiplexer):
- NEO-F0 -> NEO-G0 @ K9:
- SLOT0(48) -> SEL?(51)
- SLOT1(49) -> "PAL"(39)
(40) is a direction select for "D0~D7" (negated /ROE from 2610 sent here and RAD0~RAD7 connected to "D0~D7" of G0
(52) is a direction select for "D8~D15" (negated /POE sent here, PAD0~PAD7 connected to "D8~D15"
