And it's the newer layout - so no reworks and no ZM4 either.

But "9 available" and only one photo. So who knows what the other boards
look like.

"Condition: New – Open box" vs "Pulled from old working systems 20 years ago"... get your story straight, bro.

Yea, no filter. I think only the old layout boards have it.

The main difference between the two layouts is the position of the fan connector.

And super-early samples have a bunch of bodge wires and also a PAL at
the "spare" position ZM4 (fixing who knows what).
