- Seaview is a city in southwest Washington State, at the base of the Long Beach (Washington) peninsula.
- Southwest Washington (Wikivoyage)
Southwest Washington is a lush, forested region of Washington State. This part of the state is along north bank of the Columbia River, from where it carves a gorge through the Cascade Mountains, past the busy communities opposite of Portland, to its wide mouth at the Pacific Ocean. Its stretch of coastline features extensive sandy beaches as well as sheltered wetlands, and its interior is covered in evergreen forest punctuated with prominent volcanic peaks.
- Analyzing the vintage 8008 processor from die photos: its unusual counters (righto.com)
The revolutionary Intel 8008 microprocessor is 45 years old today (March 13, 2017), so I figured it’s time for a blog post on reverse-engineering its internal circuits. One of the interesting things about old computers is how they implemented things in unexpected ways, and the 8008 is no exception. Compared to modern architectures, one unusual feature of the 8008 is it had an on-chip stack for subroutine calls, rather than storing the stack in RAM. And instead of using normal binary counters for the stack, the 8008 saved a few gates by using shift-register counters that generated pseudo-random values. In this article, I reverse-engineer these circuits from die photos and explain how they work.
