- Castor is the second-brightest object in the zodiac constellation of Gemini. It has the Bayer designation α Geminorum, which is Latinised to Alpha Geminorum and abbreviated Alpha Gem or α Gem. With an apparent visual magnitude of 1.58, it is one of the brightest stars in the night sky. Castor appears singular to the naked eye, but it is actually a sextuple star system organized into three binary pairs. Although it is the ‘α’ (alpha) member of the constellation, it is fainter than ‘β’ (beta) Geminorum, Pollux.
- My collection of Intel 8080 microprocessors (demin.ws)
I started programming twenty year ago coding in machine codes for Intel 8080. This microprocessor was my lucky pass to the fascinating world of bits and bytes. Years later developing various emulators of i8080 and tackling with undocumented and partially documented features of this processor I decided to collect real chips from different manufacturers and examine them using the 8080 CPU Exerciser.
