 | | PDP Planet also fulfills my hope that the achievements of early computer engineers aren't lost to time. | | | These will be available through the PDP Planet Web site, as will descriptions of the work done in restoring the hardware to working condition, and recommendations for how others can leverage our restoration work for their own projects. | | | PDP Planet is a portal into the Paul Allen collection of Digital Equipment Corporation mainframes and minicomputers, where pride of place is given to two PDP-10 systems (a 2065 running the Tops-10 operating system, and a 1090 scheduled to be brought up later this year). |

| | Today, all of the PDP machines are in DEC's corporate past, with the exception of the PDP-11 family of minicomputers and microprocessors. | | | In early DEC documentation, plural form "PDPs" is used as a generic term for all DEC computers. | | | A major benefit over FORTRAN and other higher level languages that were written for the PDP where you are restricted to the functions provided in the language. |

| | PDP-11/34 |
| | The PDP line was not referred to as "computers" by Digital. | | | This was because the word computer was associated with large, expensive machines which needed a computer center and large staff. | | | Instead, it was comprised of two seperate circuit boards which performed the processor operations. |

| | PDP-11 target for lcc |
| | Now a new, versatile non-terminal, "opd" (short for operand), is introduced, which represents yet another architectural concept: an instruction operand - in PDP parlance, a source or destination field of an instruction. | | | The PDP lacks a "load effective address" instruction, so we manually construct equivalent calculations for the addressing modes above. | | | For instance, I believe it is difficult to make use of the PDP's auto-increment and auto-decrement modes, because lcc must represent the increment and dereference as separate trees, precluding templates. |

| | PDP-11 - a Whatis.com definition |
| | To dissociate their product line from these public perceptions, DEC didn't refer to the PDP as a computer at all, but used its name, the Programmed Data Processor, as a generic term. | | | DEC's first model, PDP-1 sold for $120,000 - about 40 times the price of a good computer today, but a bargain at the time. | | | Furthermore, computers of the time were so large and complex that a computer center was required to house one and a sizable staff was required to look after it. |
