The Serial Copy Management System (SCMS) is a copy protection scheme that was created in response to the digital audio tape (DAT) invention, in order to prevent DAT recorders from making second-generation or serial copies. SCMS sets a "copy" bit in all copies, which
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
These drives used Advanced Metal Evaporated (AME) tape with a 2 m integrated cleaning tape header called Smart Clean. 1999—Mammoth-2 12 MB/s data transfer rate; 4.6 cm/s tape speed during normal read/write operations; 1.6 m/s tape speed during search and rewind operations; 17 s load time, from insertion to ready
The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro Devices (AMD). It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining it with another functional core on one die, and connecting both via a shared dual-channel memory controller/north bridge and additional control logic.
The Spectravideo SV-328 is the predecessor of the MSX standard. Many MSX programs were unofficially ported to the SV-328 by home programmers. In the early 1980s, most home computers manufactured in Japan such as the NEC PC-6001 and PC-8000 series, Fujitsu's FM-7 and FM-8, and Hitachi's Basic Master featured a variant of the Microsoft BASIC interpreter integrated into their on-board ROMs.
Commodore BASIC 2.0 is used instead of the more advanced BASIC 4.0 from the PET series, since C64 users were not expected to need the disk-oriented enhancements of BASIC 4.0. The company did not expect many to buy a disk drive, and using BASIC 2.0 simplified VIC-20 owners' transition to the 64. [79] "The choice of BASIC 2.0 instead of 4.0 was ...
An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The TX-2 Tape System is the direct ancestor of LINCtape, including the use of two redundant sets of five tracks and a direct drive tape transport, but it uses a physically incompatible tape format (½-inch tape on 10-inch reels, where LINC tape and DECtape used ¾-inch tape on 4-inch reels). [6] [7]
