The two engines were built by the London Science Museum in '89-'91 for Babbages 200th birthday and in '00 they also built the printer.
The Smithsonian may have one of the engines based on the Babbage design and built by the swedish lawyer and inventor Per Georg Scheutz and his son Edvard. They sold one to the US gov in 1860. I can't find anything that may indicate that the Smithsonian ever built one for themselves.
Must be that pesky brain cell again.
Too much is never enough
I think a lot of the nonsense about directionality comes from cables (Monster comes to mind) with direction arrows on them. It has nothing to do with signal flow, but everything to do with good shielding practice. There's a rule that says signal current should never flow in shields. The usual practice is to use 2-conductor shielded cable, and only connect the shield at one end. The usual end to connect the shield is at the driven end because that's usually the quieter ground. Thus, they put an arrow on the cable that points to where the load should be connected. You can plug them in either way and they'll sound exactly the same, though possibly noise will be a tad higher or lower one way or the other.
FWIW, I can't hear the difference between interconnects. Did a test some weeks ago on the matter here-
wanna let me scramble your cables and randomly reconnect or NOT? You than come into the room and listen. Tell me what is or isn't different.
We can do this 3 or 4 times, but 20 would be statistically valid. Let me know when I can drop by and we can begin testing your hypothesis.

Unfortunately your little experiment would prove absolutely nothing. A much better experiment is take an unshielded pair of interconnects and reverse their direction. Which direction sounds best? Or even easier for the uber skeptics among us just flip a stock fuse. It's not rocket science.
I can hear directionality in interconnects VERY clearly. One direction relatively sucks. Same with fuses. Didn't you get the memo? All wires are directional, in the audible sense. Maybe you are "insensitive" to directionality. Lol
Darn, that memo was obviously sent through a cable in the "wrong" direction, so it never arrived here, or perhaps it arrived before it was sent and I missed it ;-)
