- The South Padilla Bay Unit of the Skagit Wildlife Area consists of 278 acres of mostly agricultural land at the south end of Padilla Bay in Skagit County. The four parcels that make up the unit are leased to local area farmers who produce cash crops in the summer and plant cover crops in the fall for migratory waterfowl forage. On two of the parcels, the lessee is required to plant and leave unharvested crops (typically barley) for high-value waterfowl forage. These same two parcels support three waterfowl hunting blinds managed by WDFW’s Private Lands Access Program. Due to safety concerns and to reduce disturbance to foraging waterfowl, hunting on the unit is limited to these three blinds.
- Reverse-engineering the 8086 processor’s address and data pin circuits (righto.com)
The Intel 8086 microprocessor (1978) started the x86 architecture that continues to this day. In this blog post, I’m focusing on a small part of the chip: the address and data pins that connect the chip to external memory and I/O devices. In many processors, this circuitry is straightforward, but it is complicated in the 8086 for two reasons. First, Intel decided to package the 8086 as a 40-pin DIP, which didn’t provide enough pins for all the functionality. Instead, the 8086 multiplexes address, data, and status. In other words, a pin can have multiple roles, providing an address bit at one time and a data bit at another time.
