- The 8085 processor uses a PLA (programmable logic array) to control much of the activity within the processor, such as instruction decoding and controlling the data flow between components of the chip. Pavel Zima has reverse-engineered the transistor-level circuitry of the 8085 microprocessor. I’ve looked into this in a bit more to figure out the architecture of the Programmable Logic Array, which takes up a large fraction of the chip. The PLA circuit is much more complex than the PLA on the 6502, for instance. It turns out that Pavel is ahead of me with information on the decode and timing PLAs, but the information below may still be of interest.

Northgate is a neighborhood in north Seattle, Washington, named for and surrounding Northgate Mall, the first covered mall in the United States. Its north-south principal arterials are Roosevelt Way NE and Aurora Avenue N (SR 99), and its east-west principal arterials are NE Northgate Way and 130th Street. Minor arterials are College Way-Meridian Avenue N, 1st, 5th, and 15th avenues NE. Interstate 5 runs through the district. Besides the eponymous mall, the most characteristic distinctions of the area are North Seattle College (NSC) and the south fork of the Thornton Creek watershed and Seattle Kraken Iceplex center.
