Hi Steve,
the Sharp PC-5000 bubble memory is very reliable. It`s working flawless
on two machines I have.
Bubble memory was used as well in some significant older machines, like
the Texas instruments Silent Terminals (around 77 I guess). And last
time I turned on the terminal, it worked perfectly still showing text in
memory, entered decades ago. So no worry.

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
