I have recently purchased an arcade mechine monitor. I can connect my MegaDrive, Saturn, Dreamcast, Supergun to it via RGB successfully. But I found problem with my PS1/PS2.
After some research, I figure out that the PS1/PS2 only does not got direct composit sync output. I need to extract the composit sync singal from the composit vedion output.
To do so I would need to build a simple circuit using a Video Sync Seperator Chip as follow.

The problem is I cannot found any of these chips LM1881/GS1881/GS4881/GS4981 at the local stores. (Its stucks to be living on a tiny island... )
Can any of you provide me with IC numbers of identical chips from different vendors? Or got some spare ones to sell?

Thank you Dave_K. I was able to found it in a local radio store.
I can now connect my PS1/PS2 to my new Acrade monitor.
Wow... the picture is wonderful.
I never imegin that the Saturn can displays such a betiful pictures (connecting it to the acrade monitor). I finally realize how bad the vedio encoding chips within the Saturn are. I begin to wonder, if I built an external vedio encoder (RGB -> Component or S-Vedio) and do the vedio encoding myself, would be picture of Saturn improves on my TV?
Any experiance with this idea? Anyone done it before?

- Gunbird 2 inprove a lot,
- while mushihimesama doesn't improve much.
- Screens of ESPgaluda and DDP DOJ just look like the same thing in the acrade.
