Seattle Neighborhoods: West Seattle — Thumbnail History (historylink.org)West Seattle – the oldest and the biggest of Seattle’s neighborhoods – is both a peninsula and a state of mind. The first Euro-American settlers arrived here (on Alki Point) in 1851, but left within a few months, moving to a more agreeable location on the other side of Elliott Bay (the site of present-day downtown Seattle). Orphaned at an early age, isolated by water on three sides, West Seattle has clung to its cultural independence, remaining determinedly aloof even while fighting tenaciously for the bridges, highways, and ferries that have brought it closer to its sprawling neighbor to the east.
The 8085’s register file reverse engineered (righto.com)On the surface, a microprocessor’s registers seem like simple storage, but not in the 8085 microprocessor. Reverse-engineering the 8085 reveals many interesting tricks that make the registers fast and compact. The picture below shows that the registers and associated control circuitry occupy a large fraction of the chip, so efficiency is important. Each bit is implemented with a surprisingly compact circuit. The instruction set is designed to make register accesses efficient. An indirection trick allows quick register exchanges. Many register operations use the unexpected but efficient data path of going through the ALU.
