Building a Magnetic Core Storage Interface from Scratch! Arduino, Design, Schematic, PCB, KiCad

- In this video, which is a continuation from the previous core store video, we take our old Fuji core storage device from 1967 and design a custom interface to read and write all of its core bits. And then we interact with it on a PC using a custom GUI application.
We design a custom board starting with a concept for the design, then schematic and then a PCB which we populate and finally test. We also write some firmware for an Arduino dev board to low-level interface with the core PCB unit.
This is pretty much the entire process from design to final testing. And as such, its quite a long video! Over 1 hour viewing time.
If you found this video interesting - please give us a THUMBS UP and SUBSCRIBE. That really helps us.
Leave a comment! Do you like long format videos or would you rather see smaller 10-20 minute ones. What kind of content would you like to see? More digital, more analog, CPU/MCU?. Thanks.
Good job excellent content👏
A full project! from magnetics to pcb to coding ! Great you can store a sentence in magnetic cores!
Great vid. For some of the “youngsters”, who started using computers after core memory was no longer the standard. Occasionally, you would get what is called a “slow bit”. The ferrite core wouldn’t flip to the opposite direction within the allotted time of the write cycle. One place I worked had this happen. Obviously replacing one ferrite core, in the field, was not possible. Sadly, I don’t remember what the manufacturers engineer did to remedy it. It seems like we were able to proceed with processing after the engineer worked his magic.
Very interesting, thank you!
wauw that"s something i always want to do...
You missed a trick with the video title, mention Arduino and magnetic core memory and the hits will go up. Everyone loves Arduino and obscure applications. Great explanation and implementation.. 👍👍
Arduino added!
Very nice project. I have exact the same memory module since 1985 or so. After seeing Curious Marc's video's about core memory I wanted to connect my module to an arduino. Your video is very helpfull. Perhaps I can find the energy ( due to long covid not much energy )building my own version.😊
Thats pretty cool that you have the same module. These are quite rare now. Some history checking shows these came from desktop calculators from the late 60's. Would be interested if you know what it came out of in your case. Like the Sharp Compet 32(CS-32A) or 33A. But there were a few other brands using the same boards inside. Sorry to hear of your long covid. Good luck.
@@NEEC1 I worked for the Sharp dealer in the Netherlands. Didn't repair the old compet calculators so didn't know the module came from a compet. I repaired the modern calculators an cash registers. A colleage gave me the core memory module. After searching the internet some time ago I found one same module in a Japanese museum. Thanks for your reaction. Have a nice day.
