CRT Memory
|
This is a Raytheon CK1383 "dual-gun cathode ray recording storage tube" circa 1963.
This is a advanced design of an early (before core memory) approach to data storage called
a Williams Tube.
While used in some early computers, the original Williams Tube approach had many drawbacks:
among these are very short data retention, destructive reads, and cannot read and write at the same time.
The device shown here solves these issues: it has long retention times, reads are not destructive and it is capable of simultaneous read and write. The datasheet for this interesting device is very informative. |

Univac Plated-Wire Memory Card
|
This large memory card is the plated-wire memory used in Univac 9000 series computers and the Univac 1110 in the late 1960's and early 1970's. Iron-Nickel coated wires store the magnetic field vs. ferrite cores used core memory. Plated-wire memory was easier and cheaper to produce and it also has a non-destructive read. This particular plane measures about 8 x 18.5 inches and has arrays on each side. Each side is covered with a fiber shield. |
