In 1975, the Model 32/55 computer was introduced along with a new bus architecture called the SelBUS. [10] This system was one of the industry's first true 32-bit superminicomputers along with the PerkinElmer 8/32. [11] The bus speed was 26.6 megabytes per second, which was a record at the time of its introduction.

Otter Tail initially used the SEL-21 for its fault location and event recording functions. SEL uses OTTER and TAIL as default passwords for their relays as an homage to their very first customer. In 1985, SEL built its first building and employed eleven people. In 2009, SEL became 100% employee-owned under an employee stock ownership plan (ESOP).
This is a list of software that provides an alternative graphical user interface for Microsoft Windows operating systems. The technical term for this interface is a shell. Windows' standard user interface is the Windows shell; Windows 3.0 and Windows 3.1x have a different shell, called Program Manager. The programs in this list do not restyle ...
This implies that after the hardware reset, the CPU will start execution at the physical address 0xFFFF0. In IBM PC compatible computers, This address maps to BIOS ROM. The memory word at 0xFFFF0 usually contains a JMP instruction that redirects the CPU to execute the initialization code of BIOS. This JMP instruction is absolutely the first ...

To compute an n-bit binary CRC, line the bits representing the input in a row, and position the (n + 1)-bit pattern representing the CRC's divisor (called a "polynomial") underneath the left end of the row. In this example, we shall encode 14 bits of message with a 3-bit CRC, with a polynomial x 3 + x + 1.
The reset vector for 6502 processor family is a 16-bit address stored at 0xFFFC and 0xFFFD. The reset vector for 6800 and 6809 processor families is a 16-bit address stored at 0xFFFE and 0xFFFF. No Reset Vector. For 8051 / 8080 / 8085 / Z80, reset starts code execution at address 0x0000.
