- The Mark-8 is a microcomputer design from 1974, based on the Intel 8008 CPU (which was the world’s first 8-bit microprocessor). The Mark-8 was designed by Jonathan Titus, a Virginia Tech graduate student in chemistry. After building the machine, Titus decided to share its design with the community and reached out to Radio-Electronics and Popular Electronics. He was turned down by Popular Electronics, but Radio-Electronics was interested and announced the Mark-8 as a ’loose kit’ in the July 1974 issue of Radio-Electronics magazine.
- NGC 6231 (Wikipedia)
NGC 6231 (also known as Caldwell 76 or the Baby Scorpion Cluster) is an open cluster in the southern sky located half a degrees north of Zeta Scorpii. NGC 6231 is part of a swath of young, bluish stars in the constellation Scorpius known as the Scorpius OB1 association. The star Zeta1 (HR 6262) is a member of this association, while its brighter apparent partner, Zeta2 (HR 6271), is only 150 ly from Earth and so is not a member.
