- Silicon reverse engineering: The 8085’s undocumented flags (righto.com)
The 8085 microprocessor has two undocumented status flags: V and K. These flags can be reverse-engineered by looking at the silicon of the chip, and their function turns out to be different from previous explanations. In addition, the implementation of these flags shows that they were deliberately implemented, which raises the question of why they were not documented or supported by Intel. Finally, examining how these flag circuits were implemented in silicon provides an interesting look at how microprocessors are physically implemented.
- Star Tales - Libra (ianridpath.com)
In ancient Greek times, the area of sky we know as Libra was occupied by the claws of the scorpion, Scorpius. Aratus and Eratosthenes, among others, called this area Χηλαί (Chelae), literally meaning ‘claws’, an identification that lives on in the names of the individual stars of Libra (see below). As things have worked out, Libra is now a slightly larger constellation than Scorpius, but is much less conspicuous.
- Libra (constellation) (Wikipedia)
Libra /ˈliːbrə/ is a constellation of the zodiac and is located in the Southern celestial hemisphere. Its name is Latin for weighing scales. Its old astronomical symbol is Libra symbol (♎︎). It is fairly faint, with no first magnitude stars, and lies between Virgo to the west and Scorpius to the east. Beta Librae, also known as Zubeneschamali, is the brightest star in the constellation. Three star systems are known to have planets.
