Description

Here is the description of RGB output for all MSX systems that use a DIN connector.

The RGB output connector used on MSX is generally DIN 45326 with 8-pin. There are two versions of this connector:

DIN 45326 type 8A, with pins 6,7 displaced at 45°, also called DIN 8 270°
DIN 45326 type 8B, with pins 6,7 displaced at 41°, also called DIN 8 262°

Type A has its pins laid out like a "C", or horseshoe. Type B pins instead has more the form of a "U" (See picture).

Unfortunately the differences do not end there, as the pinout also varies. Look for the relevant vendor or system below to see which pin-out and DIN type it uses.

Pinouts

Canon V-20 and Yashica YC-64 released in France

These computers use DIN 45326 type B. The pinout is described in the following table.

Pin	Name	Description	SCART Connection
1	YS	Fast switch (+12V)	To SCART pin 16
2	GND	Ground	To all SCART ground pins
3	B	Blue signal	To SCART pin 7
4	SYNC	Sync signal	To SCART pin 20
5	R	Red signal	To SCART pin 15
6	AUDIO	Audio	To SCART pin 6
7	G	Green signal	To SCART pin 11
8	AV	Slow switch	To SCART pin 8

Daewoo CPC-300, CPC-300E, CPC-400, CPC-400S, Mitsubishi ML-F80 (AZERTY) and probably ML-G1

These computers use DIN 45326 type A. The pinout is described in the following table.

Pin	Name	Description	SCART Connection
1	AUDIO	Audio	To SCART pin 6
2	GND	Ground	To all SCART ground pins
3	SYNC	Sync signal	To SCART pin 20
4	AV	Slow switch	To SCART pin 8
5	YS	Fast switch (+12V)	To SCART pin 16
6	R	Red signal	To SCART pin 15
7	B	Blue signal	To SCART pin 7
8	G	Green signal	To SCART pin 11

Fujitsu FM-X, Pioneer PX-7, PX-7(HB) and PX-V7

These computers use a DIN 45326 type A as other MSX but signals are Digital RGB output (D8A), an old Japanese standard. If you use this connector only 8 colors can be displayed. The pinout is described in the following table.

Pin	Name	Description
1	VCC	+12V (FM-X) / N.C. (Pioneer)
2	GND	Ground
3	I	N.C.
4	HSync	Horizontal sync signal
5	VSync	Vertical sync signal
6	R	Red signal
7	G	Green signal
8	B	Blue signal

Monitors that support digital RGB are rare. If you still want to use the RGB output, try the diagram below to make an adapter to RGB21. It is based on this diagram. (Not tested, the diagram is probably adaptable for the SCART.)

Gradiente MSX computers

These computers use DIN 45326 (type A). The pinout is described in the following table.

Pin	Name	Description	SCART Connection
1	SYNC	Sync / Composite signal	To SCART pin 20
2	GND	Ground	To all SCART ground pins
3	R	Red signal	To SCART pin 15
4	B	Blue signal	To SCART pin 7
5	G	Green signal	To SCART pin 11
6	DC12V	Slow switch	To SCART pin 8 and a 390R resistor to SCART pin 16
7	Y	Luma	-
8	AUDIO	Audio	To SCART pin 6

Hitachi MB-H2, MB-H3 and MB-H70

These computers use a DIN 45326 type A. The pinout is described in the following table.

Pin	Name	Description	SCART Connection
1	R	Red signal	To SCART pin 15
2	G	Green signal	To SCART pin 11
3	B	Blue signal	To SCART pin 7
4	SYNC	Sync	To SCART pin 20
5	HELD HIGH	Wired at R54 Connected to +5V	To SCART pin 16?
6	AUDIO	Audio	To SCART pin 6
7	HELD HIGH	Wired at R55 Connected to +5V	To SCART pin 16?
8	GND	Ground	To all SCART ground pins

Note: RGB connector pin-out of the MB-H70 can be changed to match that of other Japanese MSXs (Mitsubishi type) by soldering bridges on the PCB. The H bridges are for the Hitachi RGB type and M is for Mitsubishi. Make sure only one set of bridges is soldered. (Source)

Mitsubishi (Japan), National/Panasonic (except the FS-A1WSX), Sakhr, Sony and Yamaha computers + Sanyo MSX2/2+ computers

These computers use DIN 45326 type A. This is the official RGB pinout for the MSX, described in the MSX-Datapack and shown in the following table. It was used on Mitsubishi (Japan), National/Panasonic (except the FS-A1WSX), Sakhr, Sony and Yamaha computers and Sanyo MSX2/2+ computers

Pin	Name	Description	SCART Connection
1	GND	Ground	To all SCART ground pins
2	AUDIO	Audio	To SCART pin 6
3	AV	AV Control (+4.5V to +5V)	To SCART pin 8
4	SYNC	CSync 0.3Vpp / (CVBS on some machines)	To SCART pin 20
5	YS	Fast switch (+3V or +5V)	To SCART pin 16
6	R	Red signal	To SCART pin 15
7	G	Green signal	To SCART pin 11
8	B	Blue signal	To SCART pin 7

Note: The Ys pin is used to superimpose the MSX image on the receiver. But on most MSX models this pin has just a fixed voltage. It's a data pin, so do not use it as Vcc.

Panasonic FS-A1WSX

This computer use DIN 45326 type A. The connector has two functions, RGB output or CMT output/input.

Pin	Name	Description	SCART Connection
1	RGB & Audio GND	Ground	To all SCART ground pins
2	AUDIO	Audio	To SCART pin 6
3	AV / CMT GND	Slow switch (+5V) / Ground	To SCART pin 8 and CMT ground
4	SYNC	Sync signal	To SCART pin 20
5	YS & CMT IN/OUT	Fast switch / CMT signal	To SCART pin 16 and CMT IN/OUT
6	R	Red signal	To SCART pin 15
7	G	Green signal	To SCART pin 11
8	B	Blue signal	To SCART pin 7

Note: Need confirmation.
