The magnetic cores used in memory could also be used to perform logic. In fact, in the gap between vacuum tubes and reliable transistors, they were the best bet for the future. SRI apparently built an entire computer out of magnetic logic.[1]
The Elliot 803[2] was mostly magnetic logic.
Jeri Ellsworth made a video[3] demonstrating it back in 2012.
If you wanted to design a computer capable of operating in the long term on the surface of Venus... my bet would be on an extremely hot thermopile powered magnetic logic computer. Materials with a sufficiently high Curie point exist, as does insulation, etc.
