I have been lucky enough to pick up some new bubble memory gear, and now I'm
trying to figure out what I have. Any hints appreciated.
Apparently, this is a FBM-U502GU-J Fujitsu bubble memory cartridge system.
The drive is roughly 3"w x 2.5"h x 7"d, and consists of a 3-board
sandwitch.
It uses FBM-C128GA bubble memory cartridges. Interestingly, many of the
cartridges that I got have "Amdahl" stickers on them.
Anyone seen this sort of thing before?

Didn't some of the NEC or some other japanese brand laptop use bubble
memory? I wonder if it's for one of those?

There was one portable from the early 1980s that used bubble memory
internally for file storage. It's called the Teleram 3000 (I have one).
One of the TI Silent 700 terminals uses bubble memory for internal storage
of data files (it's almost a computer but not). That's the model 765.

Rumor has it that Joe may have mentioned these words:

Those are the Kyocera OEMmed laptops, namely the Tandy Model 100, 102, 200
computers had (IIRC) a 128K to 512K bubble-memory module available to them.
This was a 3rd party module - RS never supported it.
I do not know if the module worked with the other (similar but not
completely same) computers, like the NEC 8201A, Olivetti M10, or the like...
