Apple introduced the Macintosh to the nation on January 22, 1984. The original
Macintosh had 128 kilobytes of RAM, although this first model was simply called
“Macintosh” until the 512K model came out in September 1984. The Macintosh retailed
for $2495. It wasn’t until the Macintosh that the general population really became aware
of the mouse-driven graphical user interface.

On August 12, 1981, IBM released their new computer, re-named the IBM PC. The
“PC” stood for “personal computer” making IBM responsible for popularizing the term
“PC”.
The first IBM PC ran on a 4.77 MHz Intel 8088 microprocessor. The PC came equipped
with 16 kilobytes of memory, expandable to 256k. The PC came with one or two 160k
Floppy Disks Drives and an optional color monitor. The price tag started at $1,565,
which would be nearly $4,000 today.

The 4004 was the world’s first universal microprocessor. In the late 1960s, many
scientists had discussed the possibility of a computer on a chip, but nearly everyone felt
that integrated circuit technology was not yet ready to support such a chip. Intel’s Ted
Hoff felt differently; he was the first person to recognize that the new silicon-gated MOS
technology might make a single-chip CPU (central processing unit) possible.
Hoff and the Intel team developed such architecture with just over 2,300 transistors in
an area of only 3 by 4 millimeters. With its 4-bit CPU, command register, decoder,
decoding control, control monitoring of machine commands and interim register, the
4004 was one heck of a little invention. Today’s 64-bit microprocessors are still based on
similar designs, and the microprocessor is still the most complex mass-produced product
ever with more than 5.5 million transistors performing hundreds of millions of
calculations each second – numbers that are sure to be outdated fast.

ABC – 1939
The Atanasoff-Berry Computer was the world’s first electronic digital computer. It was
built by John Vincent Atanasoff and Clifford Berry at Iowa State University during 1937-
42. It incorporated several major innovations in computing including the use of binary
arithmetic, regenerative memory, parallel processing, and separation of memory and
computing functions.
