- Peering down from a Cessna floatplane circling for a landing on Seattle’s Lake Union, the airborne person can easily see the wedge shape of the Eastlake neighborhood through the clouds. Bounded on the west and north by the L-shaped Lake Union, on the east by the I-5 freeway and on the south by the Mercer Street corridor, the neighborhood sports neat rows of houseboats nine and 10 deep fingering out into the lake. The houseboats are neighbors to low rise office buildings, trendy restaurants, biotechnology firms, and the remnants of a century old history of lakefront industry. Luxurious upland townhouses rub gutters and garden gates with Victorian houses, the apartment buildings that followed them in the 1920s, and other, modest single-family dwellings. Thirty-six hundred residents currently (2001) live in Seattle’s Eastlake neighborhood.

The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Launched in 1976 and software-compatible with the Intel 8080, it offered a compelling alternative due to its better integration and increased performance. As well as the 8080’s seven registers and flags register, the Z80 had an alternate register set that duplicated them, two 16-bit index registers and additional instructions including bit manipulation and block copy/search.
