I don't recognize what they go to, but they look very different from conventional 30pin SIMMs. Even if they happen to be 30 pins, they don't look like they'd fit a regular PC motherboard.
Maybe the picture has distorted the dimensions, but even then, the jagged edge is strange and so is the number of chips on them.

I don't see any problem with dimensions - they seem like every other 30-pin simm and they are 30-pin - I counted 😉 It's just the number of chips that bothers me.

You don't think the jagged edge is strange?

Shadow from the chips? Or you mean the notch to the upper right?

Oh! Oops, I see it now. Never mind.

Dont look like its SIMMs for PCs. Maybe for some router, printer or some other proprietary equipment? Cache chips?
