Modular Spintronic Unit

A Modular Spintronic Unit (MSU) is the name used for advanced "cards" of uniform size that can be fitted into Universal Access Ports (UAPs). The name is based on the name used for the Werger Instruments MSU-series, which were actual spintronic circuit boards that could be used in modular fashion, such as in the Werger MCS.

Later modular cards developed by other corporations were also named MSUs, which lead to the name becoming a synonym for any modular card based on a specific standard.

The 7X3F standard, developed by Silverspirit Systems, eventually become the most used for large applications, as it was large enough for a quantum circuit board to be printed on. This of course requires a larger and more advanced UAP, namely a 7Q8B UAP. The 7X3F generation usually had multiple distinct circuits printed on it, and could cool itself through passive cooling. Some more advanced cards required active cooling through the UAP.

Standards
All standards were registered by the International MSU Organization, a organization founded in 2128, a long time after the release of the Werger MSU-series, which was in 2072. The part before the ';' is the general name, while the name on the right is the code. The three-letter code is the corporation abbreviation that first used the standard and the number before the three-letter code is the standard number.
