Some words about Amiga computers

There are 2 types of Amiga computers the original classic machines produced in 80 and 90, this computers have custom chips made by commodore and MC680x0 CPU.

Then there are the modern AmigaOne Computers, this computers use standard PC chips whit  PowerPC processor (short for Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC), the older mac used PowerPC, but it used mostly used in embedded systems and supper computers, in the embedded market it competes whit ARM CPU's.

The old computers are not compatible whit new computers they are currently produced by Acube Systems and AEON, instead AmigaOS4 is responsible for compatibility whit the software side, there are two built in ways AmigaOS4 can execute 680x0 binary, one by translation so called JIT, the other way is using a interpreter where etch oppcode is looked at and  executed as the program runs, AmigaOS4 is also runs native PowerPC code, most of the OS is PowerPC, but there are a few components that is in 680x0 binary format.

Because new AmigaOS4 hardware do not have the old chips produced by commodore and because developers of the time did not know to write code so you can replace audio output or video output, its not always possible to run every thing, the old games and programs that do work we call system friendly.


  1. Hi there,

    We live in interesting times when it comes to Amiga computers. As you probably know, an AmigaOS 4.x compatible netbook will be released in the first half of 2012. Can't wait. :) I no longer have an AmigaOS 4.x machine, so it will be nice get back in business with a netbook. At the moment I use an Amiga 1200 for creative purposes and a CD32 for gaming. :)

    Looking forward to read more posts from you in the future. :)

  2. Yes its interesting times, netbook is interesting first computer I can take whit me, whit taking hundreds of cables and drag the monitor around, I'm also interested in this.
