I've always been a fan of bubble memory, although I have no
functional bubble subsystems here. I've seen S-100 and Q-bus bubble
memory boards (the latter I missed on eBay by a few dollars maybe a
year ago), and there's at least one piece of test equipment made by
Fluke (I don't recall which one) that uses bubble memory cartridges.
I also have some brand new Sharp CE-100B cartridges, but no machine
to use them in.
