My initial interest was driven by the osloom project (an open-source Jacquard Loom)...
Sadly the project appears to have stalled, hopefully it'll restart at some point.
On a more modern take, I'll plug the OSLOOM project, which aims to create "an open source electromechanical thread-controlled floor loom that will be computer controlled." It's been slowly ticking along for some time now; hopefully it'll eventually achieve its goals of enabling much cheaper access to a modern Jacquard loom.
These are antique looking jacquard looms in current use in Hanoi. I bet they are still there right now, operating. I know that some crafters use them and there are still specialty mills that make use of modern jacquards, but this is a factory and these look like they are straight out of the 1800s. Amazing.
I wonder still how old some of those looms are...
I wonder if the equipment you saw in Hanoi passed through China on its way.
The Jacquard loom contains a distant forerunner of the punchcard used in large numbers to emulate a ROM with a program, making it the first programmable piece of industrial machinery.
Here's a review by Stuart Reeves:
It'd be neat to see a loom take either punch card or textile as input. So you could write to the textile, use it as memory and instructions. Then when the program is finished just cut it up and make a rather fetching cardigan from it (the textile, not the punch cards - silly!)
If you're in the UK and want to see a real Jaquard Loom, there's currently one on display at the Science Museum in London.
