cool operating system

the truth is not that MICROSOFT copied off from LINUX. for instance, using AMIGA OS, you can hold the shift key, and click a text block- what will happen? it will become selected. and this OS is from 1985. it is believed it has been prototype for WINDOWS!

and nowadays, virtual AMIGA can even use WINDOWS directory as hard drive.

i made this video to give you an idea of the computing power of this game console. crunching (here called imploding) of a 600K file takes about 3 minutes!

and of course, nowadays it is not required anymore. a real amiga 500 would be much slower as well.
this is a 68040 system at high speed, megabytes of memory, and large hard drive.

so if you do not want to use WINDOWS and WORD all day, why not try the AMIGA OS? it can use files from your windows hard drive, even USB if you want to. but the old 1.3 OS can not show JPEG pictures, or play movies. if you look for such features, you need the 3.1 AMIGA OS, or something different.

you can use the AMIGA for text writing, for old games, to learn C programming! fully legal, and much better than under LINUX. later it was watered down into many different OS types, like on LINUX, but traditionally, there is only 1.3, 2.0, and 3.1 OS. they used to be shipped with real AMIGA computers until the year 1994.

if you use later OS, like the 3.5, 4.0 or AROS, you can have most features you find on WINDOWS etc, but it is not the same thing anymore. there are even POWERPC amiga's manufactured freshly as of today (in small numbers).
you could use such an amiga for video animation (it can record to a video recorder, or display on TV screen much easier).

if you just want to discover the AMIGa, try the 1.3 or the 3.1 OS (and ask someone for some cool game titles).

besides, you can have a file shell, including multitasking, and a graphical workbench if you wanted to. there is no one stopping you to use it as windows shell (besides that performance may go down a little). it depends what you want to do with it. by default, you can for instance repeat previous commands, can assign real volume names, can have complex scripts...and all this since the 1.3 OS.

installation is not very dramatic. AMIGA OS 3.1 can fit into less than 1 megabyte if required (most game players do not need the system commands). you could delete them, but why would you want to? because you can use hard drive easily.

it could even be said that there is no installation (at least, under 1.3 OS). just attach the floppy disk image!
however, making programs work under 1.3 requires special knowledge, which even can not be found in the official manuals. for instance, you need to know the program names, where to download them, and how to install additional libraries (for instance, file requesters, think it was the year 1987!).
it is unknown how many new people the amiga platform will or still can attract.
most users will be from the 1980s with real experience.

but i like it much more than linux.
what amiga os 1.3 is doing can be explained on 1 or 2 thousand pages, and the commands are maybe 50 or the like. it can startup within a few seconds, and is not doing very much on its own.

The Amiga 500, also known as the A500 (or its code name 'Rock Lobster'),was the first low-end Commodore Amiga 16/32-bit multimedia home/personal computer. It was announced at the winter Consumer Electronics Show in January 1987, at the same time as the high-end Amiga 2000, and competed directly against the Atari 520ST. The A500 was released in mid 1987 at the price of 595.95 USD without monitor. The 500 represented a return to Commodore's roots, being sold in the same mass retail outlets as the Commodore 64 to which it was a spiritual successor, as opposed to the computer store-only Amiga 1000. The original A500 proved to be Commodores best-selling Amiga model, enjoying particular success in Europe.Although popular with hobbyists, arguably its most widespread use was as a gaming machine, where its advanced graphics and sound for the time were of significant benefit. Like its predecessor, the Amiga 500 uses a Motorola 68000 microprocessor running at 7.15909 MHz in the NTSC version or 7.09379 MHz in the PAL version. While the 68000 is a 32-bit chip internally, it has a 16-bit data bus and 24-bit address bus, providing a maximum of 16 MB address space. Also like the Amiga 1000, the 500 uses the OCS chipset. Graphics can be of arbitrary dimensions, resolution and colour depth, even on the same screen. Without using overscan, the graphics can be 320 or 640 pixels wide by 200 (NTSC standard) /256 (PAL standard) or 400 (NTSC interlace)/512 (PAL interlace mode) pixels tall. Overscan mode enabled 700 x 600 resolution in PAL machines.Planar graphics are used, with up to 5 bitplanes (4 in hires), allowing 2, 4, 8, 16 and 32 colour screens, from a palette of 4096 colours. Two special graphics modes were also included: Extra HalfBrite, which used a 6th bitplane as a mask that halved the brightness of any colour seen, and Hold And Modify (HAM), which allowed all 4096 colours on screen at once. Later revisions of the chipset made PAL/NTSC mode switchable in software. Sound is 4 hardware-mixed channels of 8-bit PCM sound at up to 28 kHz. The hardware channels had independent volumes (65 levels) and sampling rates, and mixed down to two fully left and fully right stereo outputs. Each channel is designated another channel for which it can optionally modulate both volume and frequency using its own output. A software controllable low-pass audio filter is also included. The machine came standard with 512 KB of Chip RAM and AmigaOS 1.2 or 1.3. One double-density floppy disk drive is included, which is completely programmable and thus can read 720 KB IBM PC disks, 880 KB standard Amiga disks, and up to 984 KB with custom formatting (such as Klaus Deppichs diskspare.device). Breaking with the Amiga 1000, and in keeping with the home computer tradition established by the VIC-20 and C64, the A500 had its keyboard integrated with the CPU unit, although the floppy disk drive is also integrated, unlike the 8-bit models. The 500 used the standard Amiga two-button mouse. Despite the lack of Amiga 2000-compatible internal expansion slots, there are many ports and expansion options. There are two Atari 2600 DE9M sockets for joysticks or mice, stereo audio (RCA connectors 1V p-p). There is a floppy drive port for daisy-chaining up to 3 extra floppy disk drives via an DB23F connector.The then-standard RS-232 serial port (DB25M) and Centronics parallel port (DB25F) is also included. The power supply is (+5 V , +/-12 V).The Amiga 500's graphics are output in analogue RGB 50 Hz PAL and 60 Hz NTSC video output, provided on an Amiga-specific DB23M video connector. It can drive video with 15,75 kHz HSync for standard Amiga video modes but this is not compatible with most VGA monitors. A Multisync monitor is required for some higher resolutions. This connection can also be genlocked to an external video signal. An RF adapter was bundled with the machine to provide output on regular televisions. Monochrome video is available via an RCA connector. There is a Zorro II bus expansion the left side behind a plastic cover and a trapdoor slot under the machine, for RAM expansion and real-time clock.
