One of my favorite backwaters of technology is the work they did in the 50's and 60's with "cryotrons", which were essentially like superconducting transistors that switched by one superconductor temporarily destroying another's superconductivity. They apparently even made a working memory module out of them and provided it to the NSA before the transistor came along and changed everything. |
