- The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features. However, it requires less support circuitry, allowing simpler and less expensive microcomputer systems to be built. The “5” in the part number highlighted the fact that the 8085 uses a single +5-volt (V) power supply by using depletion-mode transistors, rather than requiring the +5 V, −5 V and +12 V supplies needed by the 8080. This capability matched that of the competing Z80, a popular 8080-derived CPU introduced the year before. These processors could be used in computers running the CP/M operating system.
- Cypress Island (wa100.dnr.wa.gov)
Hop into a kayak and paddle over to Cypress Island for a true Salish Sea experience away from the crowds. The island is the largest relatively undeveloped land mass in the San Juan archipelago. With an extensive network of hiking trails and two campgrounds, much of this island is accessible to visitors. Day-use areas with names like Smugglers Cove and Secret Harbor promise a peaceful afternoon by the beach. The Washington State Department of Natural Resources has designated portions of Cypress Island as a Natural Resources Conservation Area and Natural Area Preserve, which collectively protect 6,000 acres of diverse ecosystems such as forest, wetland, grassland, shoreline, and tidelands. The unique geology here is critical to these ecosystems, so leave your kayak behind and pay attention to the rocks and soil underneath your feet as you make the 6-mile trek across the island.
