The second half of major recurring enemy reconstructing an alien program stored in bubble memory on an early 1980s Earth-based computer system.

Rockwell was also a pioneer in solid-state storage devices, introducing " bubble memory " non-volatile expansion boards about 1980.
13.
He invented the twistor memory in the late 1950s, and in the late 1960s bubble memory based on magnetic domains in orthoferrites and garnets.
14.
Bubble memory was used for some time in the 1970s and 80s where its non-moving nature was desirable for maintenance or shock-proofing reasons.
15.
Additionally, a tiny amount of lutetium is added as a dopant to gadolinium gallium garnet ( GGG ), which is used in magnetic bubble memory devices.
16.
Bubble memory started out as a promising technology in the 1980s, offering memory density of a similar order to hard drives but performance more comparable to core memory.
17.
In particular, its soon-to-arrive competitors ( including the Grid Compass ) made use of the new Bubble memory technology to provide non-volatile memory.
18.
Over the history of computing many different memory cell architectures have been used including core memory and bubble memory, but the most common ones used are flip-flops and capacitors.
19.
Bobeck had worked on many kinds of magnetics-related projects through the 1960s, and two of his projects put him in a particularly good position for the development of bubble memory.
20.
The project would consist of creating a micro satellite containing a non-volatile bubble memory chips wrapped in a sphere or American football-shaped photovoltaic panels powering a simple radio transmitter.
