"TYPE 3" is used in Renault Laguna 1 (x56) / 1994-2001

- It is a Sample based system

- The speech synthesizer hardware is integrated into the cluster. (Cluster must have green connector [HIGH version])

- Languages: French, English, German, italian, Spanish, Dutch

PHASE 1:

Phase 1 parts have a seperate distance counter display in the center of the cluster. Phase 1 uses a red, a blue and a green connector.

PHASE 2:

Phase 2 parts show the distance counter in the upper borardcomputer display. Phase 2 has a red, a grey and a green connector. Phase 2 uses different connectors. 

Phase 2 speech synthesizer hardware:

ROM : 44PIN OKI M531602C (DATASHEET) (2MB)

FPGA : PIOLOGO3  (Toshiba) TC110G08AF* (DATASHEET)

MICROCONTROLLER : Texas Instruments TMS370C056 (DATASHEET) and D36011FNA (UNKNOWN)

* I´m not sure if "PIOLOGO3" is the speech synthesizer... At least it has direct connections to the voice ROM... Maybe it is a FPGA or something like that. If you search for the number below PIOLOGO3 (TC110G08AF)  you will find some old Harddisks with this chip... I am pretty sure a Harddisk does not have a speech synthesizer...

EDIT: I was right... it is a gate array. TC... sounded a lot like a partnumber from Toshiba. some searches later i found the Toshiba TC110G gate array in the version 08 (TC110G08) with around 3200 usable gates. >DATASHEET<... I have to make some measurements to see wich of the IC´s generates the Voice output that is fed into the amp... 

I finally found a ROM Chip that looks exactly like our MASKROM ... I think its time to order a adapter so that i can try to dump it... M27C160 (DATASHEET) seems to be the regular version of the MSM531602E
