PSX RGB to Amiga 1084 Adaptor

[Administrator]

Made this in 1 night. Just waiting for it in the mail.
It will take the PSX RGB, invert the sync, and output it to a Commodore Amiga 1084 monitor (the exact model in the picture below). The 1084 monitor requires an inverted sync, while the 1084S does not. This PCB will provide a crystal clear RGB picture for you if you need to invert the sync signal. The pinouts are in a post below.

NOTE: This PCB is not required for the second version 1084S monitor.
Ignore the silkscreen text on the back of the PCB that has '1084-S'.

If you're confused, this mod is only for the monitor seen below (1084 or 1084S).

Just waiting for the 220K pot and the jumper cables.

Yes, it will work with the PS2. It will work with any RGB signal.

This product for 1084 monitor,I have 1084s monitor,what can i do for ps1 ?

[Administrator]

Wire it straight to the monitor. You just need R, G, B, SYNC and GND.
The pinouts for the second 1084S model with the DB-9 connector and PSX MULTI-AV out connector are on the Internet.

PSX R to 1084S R
PSX G to 1084S G
PSX B to 1084S B
PSX Composite Sync to 1084S Composite Sync(or H-Sync)
PSX GND to 1084S GND

You don't need a resistor or filter capacitor.
You need to change modes on your 1084S monitor using the buttons on the back

No work, there must be something else?

Did you push in the 'ANALOG TTL' button on the back? All the other buttons should not be pressed in.
You do not need the PCB for the monitor you have shown since that's the second model.

[ibiliguk]

I've tried all of them, are mutually pin numbers?
yes, it works nicely amiga and c64:)

I did s-video cable for ps and ps2:

[Administrator]

Well according to my documents, the pins for ANALOG RGB (TTL) on your 1084S are:
Pin 1: GND
Pin 2: GND
Pin 3: Red
Pin 4: Green
Pin 5: Blue
Pin 6: N/C
Pin 7: Composite Sync
Pin 8: H.Sync
Pin 9: V.Sync

Looks like your pins are wrong
I have this monitor (second version seen directly above in your post), and it works perfectly for the PSX.
