Possible original trilogy chip board casting

[robstyle]

During some Episode 3 work I came across an old plaster cased brittle silicone mould that, if memory serves, was marked SW chipboard. The white casting was still in the mould. After a painstaking amount of time I freed that casting with minimal damage to the mould. I did a dump pour with better quality material and the silicone broke up upon demoulding which was expected.

Anyone have any ideas of where it may be or what's its use was in the films? Mouse Droid is first to come to mind but is there any chance the castings were cut down for use in other areas?

Could be lukes land speeder too

Side panels for the mouse droid(s) were the first thing that came to my mind as well, but I remember similar panels being used above the radios on the rear of the speeder as well...

Great find!

There are definitely some exposed areas of the Falcon in ESB that had the same type of populated board as the mouse droid.

This is wonderful, thank you for sharing!

The size of those PCB boards remind me of those tall wooden arcade games and sound mixers. Those boards were massive.

Now that I think about it, those "Coin slots" on R2-D2 and Darth vader look like those volume slider pcb shrouds on sound mixers. Helps that alot of the aforementioned have "cooling vents" aswell.

Gotta look for it.

*Edit* since I counted 116 chips, the closest example I could find was of a CNC mill PCB.

But here's an example of an arcade PCB.

In ROTJ are any chiobqirds used anywhere? Endor bunker interior or wall, inside the Chicken Walker interior mock up, sail barge...

Goodness what a find!! Is that "M" the only marking you can see on the board?

 

[robstyle]

Looks like there are Other letters I J K L M N O no idea if that's from the original found parts or added for cast parts reference. Seems it's along side of the found part and not part of it. But I could be wrong.

I thought it would be good to note that the closest I've been able to find to the V2s clamp card are from CNC and Arcade boards. That cant be a coincidence

 

[Pedro]

The clamp cards are a .156 spacing edge connector, was somewhat common as a standard back then, all but gone today JAMA and other arcade boards used this, as well as a variety of industrial stuff like the Otis Elevator boards. I have a variety of boards with the correct spacing, but few with accurate-ish leads, and none with the traces turning a corner like on the V2. No idea what that was of course!

Ok, I see some of the other letters now. Probably alphabetical indicating the row of chips?
