Mini (Mid
Ranged) Computers

Computer that possesses the same components as large
mainframes but has reduced memory and slower
processing speeds.

computers that are more powerful and capable than
personal computers but less powerful and capable than
mainframe computers.

8 was the first successful minicomputer.

It was created Edson de Castro a computer engineer who
later founded Data general.


12 bit

sold more than 50,000 systems.

First 16
bit minicomputer.

Served as the basis for two generations of HP’s desktop
calculators and computers

It was originally intended as a instrument controller, but
due to a relatively small market for instrumentation
controllers, and result of its success in the business
computing market. It was re
engineered and introduced
as cost
reduced versions called the HP 2115A and HP
2114A minicomputers.

First emerging in the 1960’s the mini
computer quickly
became popular in both the business and science
community due to its smaller size and capabilities to get
the job done.

The first minicomputer was a 12
bit. It was capable of
attach peripherals like printers and could handle word
processing and other simple tasks.

The success of the first minicomputer gave rise to other
minicomputer such as Data General, Wang Laboratories,
Apollo Computer, and Prime Computer

Small businesses had no need and no space for large
mainframe computer systems. So the minicomputer often
offer small business with what the needed and could do it with
out taking up a whole room of space.

In 1970 an 80’s when the first micro
computers came out they
were mostly low powered single user machines running
simple program
launcher operating systems like CP/M or MS
DOS. While Minis offered more powerful systems that ran
full multi
user, multitasking operating systems that business

Minicomputers filled the mid
range area between low
powered microcomputers and high capacity mainframes.

During the 1990s the change from minicomputers to
inexpensive PC networks was cemented by the
development of several versions of Unix to run on the
Intel x86 microprocessor.

Microsoft Windows series of operating systems,
beginning with Windows NT, now included server
versions that supported preemptive multitasking and
other features required for servers.

As microprocessors have become more powerful, CPUs
built up from multiple components have become
increasingly obsolete.
