- Macintosh 512Ke (Wikipedia)
The Macintosh 512K enhanced (512Ke) was introduced in April 1986 as a cheaper alternative to the top-of-the-line Macintosh Plus, which had debuted three months previously. It is the same as the Macintosh 512K but includes the 800K disk drive and 128K of ROM used in the Macintosh Plus. The new ROM supported HFS used on 800K and larger disks and allowed the Hard Disk 20 to be used as a startup disk, doing away with the Hard Disk 20 Startup floppy required by the prior Macintosh 512K. Like its predecessors, the 512Ke has little room for expansion. Some companies did create memory upgrades to bring the machine up to 2 MB or more.
- Torx (Wikipedia)
Torx (pronounced /tɔːrks/) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967 by Camcar Textron. A popular generic name for the drive is star, as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. This is sometimes abbreviated in databases and catalogs as 6lobe (starting with the numeral 6, not the capital letter G). Torx Plus, Torx Paralobe and Torx ttap are improved head profiles.
