No special provisions for rad hardening needed?

Please write an article about that French computer Project idea: find 64kb kb of such memory and connect it somehow into Apple2, atari and other 8bit cpus hehe

It must be possible to have some hardware adapter to map RAM into that type of memory.

Or even over serial...

ps. Related story: around 10 years ago Texas Instruments started to use FRAM in some of their 16 bit MCUs (msp430 family)

It works exactly like core memory - data still intact after power resets.

I've already written articles about the French computer and FRAM; enjoy :-) https://www.righto.com/2026/05/reverse-engineering-spacelab-... https://www.righto.com/2024/09/ramtron-ferroelectric-fram-di...

FRAM is a somewhat common retrofit for battery-backed SRAM: https://bastelblog.runlevel3.de/en/restore/ds1250-fram-repla...
