How "stable" is bubble memory, over decades? There is a Sharp PC-5000 that may be available, I believe from 1983-1985 era, which is said to have bubble memory. But the owner can't find a power cable, to verify if anything still works.
I have older systems with ICs that are still working OK, but I was wondering thoughts on any risk associated with bubble memory? (likelihood of not working at all, or being damaged in long distance shipping) Actually another thought, can any "normal" ICs be used to replace/substitute the bubble memory? Regards, Steve
