Amiga
Beginning:
Everything
started Jay Miner in 1980, when he wanted to do new generation computer,
based on MC68000 processor.
He left Atari and with Dave Morris, opened Hi Toro firm.
Morris (producer) named projekt, Lorraine (name of his wife).
At least, project name were changed to spanish, Amiga (girl friend).
When graphic chips were done, Carl Sassenrath did first multitasking
operating system.
Everything was first time shown at Consumer Electronic Show (CES) in 1983
(there was first and popular amiga demo known as Boing Ball - jumping
red'n'white ball).
Amiga Inc become bought by Commodore, which did swobode in their project
creating.
23 July 1985 in New York shew first version of Amiga 1000.
Prince for A1000 was over 2000$, when for PC286 was 4000$.

29 April 1994 Commodore fell, and then it become
ransomed in April 1995 by Escom.
They did anything, beyound let A1200 (with Kickstart 3.1) & A4000T
out.
Subsequently, come into being Amiga Technologies, which on Cebit 96 showed
new amiga prototype named Mind Walker with Kickstart 3.2 (known
also in working titles A1300 & A1200+).
21 June 1996 AT become reselled to Viscorp, and in 2000 to GateWay (they
try to do new model, AmigaNG, but after 2 years, they changed plans).
Currently, Amiga Inc is administered by Mc Ewen.

AAA
(Advanced Amiga Architecture) (64-bit)
(Secret project initiated by Commodore around 1989 to create the
next generation of Amiga technology.
This Chipset was never finished.)
Andrea - controlls all Chip-RAM activity, manages the chip bus and
video display clocks and video timing control.
Linda - double-buffered line buffer, which makes it possible to run
pixels and the chip bus at different clock rates, and also does some
compression tricks.
Mary - Audio, floppy and I/O controller
(8 channel stereo, 16-bit, 100 kHz, audio can be digitally mixed to
18-bit)
Monica - Display controller, displaying the timing & graphics
data, responsible for chunky and planar modes, HAM/HAM8, true color
and 10-bit HAM mode for 24-bit display |
System can run 1280 x 1024 at around
11-12 bits/pixel at 60 Hz
(many other resolutions are possible, including all older).
System supports planar displays to 16-bit, as well as chunky displays,
HAM8, HAM10 and HAM8-chunky.
