Are PDP-11 still in use?

Are PDP-11 still in use?

The PDP-11 is definitely still in use today, thanks to its unique and strong build. It is still used to power a GE nuclear power-plant robotic application — and will do so until 2050. Technically, due to its potency, it is still used by the US Navy in its ship radar systems and by Airbus SAS.

Does the PDP-11 use memory mapped I O or directed port I O or both?

There are no specific input or output instructions; the PDP-11 uses memory-mapped I/O and so the same move instruction is used; orthogonality even enables moving data directly from an input device to an output device.

How much RAM did the PDP-11 have?

4 MB
Later-model PDP-11 processors included memory management to support virtual addressing. The physical address space was extended to 18 or 22 bits, hence allowing up to 256 KB or 4 MB of RAM.

What PDP means?

Which minicomputers do you know?

Minicomputers are mainly multi-users systems where more than one user can work simultaneously. Mini computer examples: IBM’s AS/400e, Honeywell200, TI-990. Minicomputer can support multi-users at a time or you can say that minicomputer is a multiprocessing system.

What killed Digital Equipment Corporation?

“Digital Equipment Corp. had microprocessor technology, but its business model could not profitably sell a computer for less than $50,000. The technology trapped in a high-cost business model had no impact on the world, and in fact, the world ultimately killed Digital.

Why did the Xerox Star fail?

The Xerox name alone was considered their greatest asset, but it did not produce customers. Finally, by today’s standards, the system would be considered very slow, due partly to the limited hardware of the time, and partly to a poorly implemented file system; saving a large file could take minutes.
