i disassembled one ops 940nd which had some mechanical defects (2 of the screw-sockets are broken out)

from what i can tell http://pinouts.ru/CellularPhones-A-N/sagem_9xx_pinout.shtml this pinout comes close enough.

the pins are staggered in a up-down pattern on this device, and not in a linear row, but the numbers make sense. the one closest to the coax (1) is plus, the gnd os on pin6 or coax shield.

for daily fnord: this phone seems to be a completely different phone wrapped into 2 extra add-on boards (new keyboard/display pcb and backshell pcb to adapt different battery)
