instruction set are unusual, most notably the byte instructions, which operated on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as a contiguous sequence of a fixed number of bits. If all those bits are E qual to zero, skip the next instruction; and in any case, replace those bits by their boolean complement. Zork was written on the PDP-10. There are three main classes of instruction: arithmetic, logical, and move; conditional jump; conditional skip (which may have side effects). 208, "It was largeeven DEC's own literature called the PDP-10 a mainframe." Ceruzzi,. Nhésitez pas à venir en mairie pour savoir si ces objets perdus vous appartiennent. While many attributed the success of the PDP-11 to DEC's decision to make the PDP-11 Unibus an open architecture, DEC reverted to prior philosophy with the KL, making massbus both unique and proprietary. Consequently, there were no aftermarket peripheral manufacturers who made devices for the massbus, and DEC chose to price their own massbus devices, notably the RP06 disk drive, at a substantial premium above comparable cite de rencontre non payant en valence IBM-compatible devices. Its cycle time is 1 s and its add time.1. PDP-10 processor augmented by special paging hardware "DECsystem-10/decsystem-20 Processor Reference Manual" (PDF).
