- 8080 PL/M Compilers Operator Manual (bitsaver.org)
This manual describes the operation of the INTEL 8080 PL/M* Cross Compiler. The compiler comprises two distinct programs written in ANSI standard FORTRAN IV and may be installed on most medium to large scale computer systems. Some details presented in this manual may vary due to system dependencies and compiler options selected during the installation process. The PL/M language itself is described in the 8008 and 8080 PL/M Programming Manual.
- PL/M-80 Programming Manual (bitsavers.org)
A PL/M program is a sequence of PL/M statements. The PL/M-80 Compiler accepts the statements as input and produces a machine-code program module as output. As will be seen in the remainder of this chapter, a PL/M statement may be translated by the compiler into a single 8080 instruction, or a sequence of instructions, or none at all–it may cause the compiler to allocate storage, for example, instead of producing any machine instructions.
- Columbia River Basalt Group Stretches from Oregon to Idaho (usgs.gov)
The thick, layered lava flows of the CRBG erupted as flood basalts, which originate as some of the most highly effusive eruptions in the world. The CRBG sequence a classic example of flood basalt activity that erupted more than 350 lava flows from about 16.7 Ma to 5.5 Ma. The eruptions originated from a series of generally north-northwest-trending linear fissures, ranging from tens to hundreds of kilometers in length, located along the Washington/Oregon/Idaho border. The magma that fed these massive eruptions may have come from a plume-like upwelling from the mantle called a hot spot. Since the time of the CRBG eruptions, the North American plate has moved in a west-southwestwardly motion, and that hot spot is now believed to reside beneath Yellowstone volcano in northwest Wyoming.
- PL/M (Wikipedia)
PL/M, an acronym for Programming Language for Microcomputers, is a high-level language conceived and developed by Gary Kildall in 1973 for Hank Smith at Intel for the Intel 8008. It was later expanded for the newer Intel 8080.
