- The Celtic Sea is the area of the Atlantic Ocean off the southern coast of Ireland bounded to the north by Saint George’s Channel; other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, parts of Devon and Brittany. The continental shelf, which drops away sharply, delimits the southern and western boundaries. The Iroise Sea off Brittany is entirely included within it. The Isles of Scilly are an archipelago of small islands in the sea.
- 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.
