Yeah, the a/v cable is proprietary. The power cord is just as you described - just a standard cord. It's just like the ones that fit the old gray Playstation 1 models. (you can swap between the two). I do have couple extra controllers (all in decent shape).
SYSTEM1Model 1 Saturn: some scuffs on the shell, installed US-JP region switch between controller port.

SYSTEM2Another model 1 Saturn, no region switch (completely stock). Some scuffs on the shell.

SYSTEM3Model 2 saturn, US-JP region switch installed next to cart slot. Shell in pretty good shape.

PM me an offer I can't refuse.

They'd be shipped out from Canada.
