Minicomputer today
The PC and servers we use today are clearly microcomputer. You can read about Mainframe computer here. More small version is Netbook. Basically the Operating System of a Minicomputer is actually used UNIX OS. Microsoft copied the idea of their Operating System from both VMS and UNIX.
What was the DEC?
DEC identified a demand for more affordable and high-performing computing systems that could be used in scientific research and other technological settings. DEC introduced a mid-range computing solution, the minicomputer, at a time when the alternative was too bulky and costly for most people. Digital paper tape, circa 1970s.
When did DEC start selling computers?
DEC began selling its first computer at the end of 1960. But it was aware of people’s reluctance to invest in “computer” technology at the time, so it named the computer a “programmable data processor”, or PDP. The first iteration of this product line (PDP-1) sold for $120,000 that year.
Why did Digital Equipment Corporation fail?
Almost unanimously, they supported the theory—also commonly held by experts—that the failure of the company ultimately fell to the leaders who were unable to foresee what was coming in personal computing and were not able to take decisive or quick enough action in time to save the company.
How many PDP variants were created by DEC?
Throughout the remainder of the decade, DEC created over a dozen PDP variants.

In 1963, DEC introduced what is considered to be the first commercial minicomputer in the form of the PDP-5. This was a 12-bit design adapted from the 1962 LINC machine that was intended to be used in a lab setting. DEC slightly simplified the LINC system and instruction set, aiming the PDP-5 at smaller settings that did not need the power of their larger 18-bit PDP-4. The PDP-5 was a success, ultimately selling about 50,000 machines.
