The software for simulation of historical computers, SIMH, contains modules to emulate all the PDP-10 CPU models on a Windows or Unix-based machine. Copies of DEC's original distribution tapes are available as downloads from the Internet so that a running TOPS-10 or TOPS-20 system may be established.
Model As used the original PDP-10 memory bus, with external memory modules. The later Model B processors used in the DECSYSTEM-20 used internal memory, mounted in the same cabinet as the CPU. The Model As also had different packaging; they came in the original tall PDP-10 cabinets, rather than the short ones used later on for the DECSYSTEM-20.
PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
The PDP-10 was widely used in university settings, and thus was the basis of many advances in computing and operating system design during the 1970s. DEC later re-branded all of the models in the 36-bit series as the "DECsystem-10", and PDP-10s are generally referred to by the model of their CPU, starting with the "KA10", soon upgraded to the ...
The mass storage drawers, in such a case, would be divided between the CPU drawers, with a minimum of one per a CPU drawer. It included two models of mass storage drawers. One model may contain one to four 5.25-inch full-height non-removable, one 5.25-inch full-height removable or non-removable and two 5.25-inch half-height removable devices.
5.6 Macintosh with 680x0 CPU. 5.7 Macintosh with PowerPC CPU. 5.8 Atari ST/STE/Falcon. ... DEC PDP-10: PDP-6, KA10, KI10, KL10A/B, and various very old computers
The PDP–11/45 had a dedicated data path within the CPU, connecting semiconductor memory to the processor, with core memory and I/O devices connected via the Unibus. [10] In the PDP–11/70, this was taken a step further, with the addition of a dedicated interface between disks and tapes and memory, via the Massbus. Although input/output ...
In a stand-alone configuration, the PDP-11/10 within the terminal can be expanded with additional memory and any PDP-11 family peripheral to build as complex a system as necessary. “In fact, the central processor used in the GT-40 can be any PDP-11 family processor,” says Mucci, ”since the display processor is interfaced via the PDP-11's ...
