Glad to see any video demonstrating this fantastic machine of the late 60's. I am trying to re-produce the magnetic core memory as well as the actual sense circuit but wondering if you have any spec information on the TDK PT-1611 sense transformers used.

Thanks for your comment. It's a wonderful project. But unfortunately I have no information on that component.

@@ryomukai Thank you anyway. I hope to hear from TDK if they have any historical data on that part, otherwise I am trying to make my own but it sure is not easy ;-) If I ever come across a AL-1000 then I would treasure it forever as I am sure there are not many left out there 🙂
