The 68000 only has 16-bit bus so it was not generally considered a full 32-bit CPU back in the day.  The Atari ST's name alludes to this; it stands for Sixteen/Thirty-two (and perhaps also Sam Tramiel).  The TT had an 030 so was Thirty-two/Thirty-two.


The 68000 only has a 16 bit DATA bus. The address bus is 23 bits. The general purpose registers are 32 bits.

Data bus: 16 bits
Address bus: 23 bits
Address Register Size: 32 bits
Data Register size: 32 bits
Instruction size: variable (multiple of 16 bits)

As far as programming goes, it looks and acts like 32 bits. You are right that it is generally considered a 16/32 bit hybrid CPU.

It is impossible to code Amigas in 16-bit as there is no such thing as a 16-bit Amiga.

All Amigas ever built can only be programmed in 32-bit because they have 32-bit CPUs.


Hi,

Check your specs, all amigas that use the 68000 series motorola are 16/32.

I know I am being picky.

I am now listening to Amiga MODS with VLC on Ubuntu 11.10, funny how you can make Linux act like an Amiga without a EUAE.
I have no idea what your talking about, so here is a doggy with a small pancake on his head.

MorphOS is a MAC done a little better

OCS and ECS are 16bit and so is the DMA bus architecture for chipset<->CPU<->RAM. As you are programming the 16bit OCS/ECS and all chip/fast memory access is 16bit so your games are running on a 16bit computer ergo they're 16bit games.

Calling Amiga 500/600/1000/1500/2000 32bit systems is as wrong as calling the Atari Jaguar a 64bit console.

Thanks for that Digiman..... :)

@ChaosLord
Actually that review you gave me was really fun to read, I really enjoyed it! Cos I've never ever seen a games review that gave a game a complete 100%. And it was so honest to boot....best review ever! :D

@Tripitaka
I had a look at Desert Racing of BarDos...it doesn't look bad at all! Read the comments too...some felt it needed more memory to run or have it ported to PowerPC. But it looks good! :)


Generally speaking though, I'm REALLY REALLY surprised no one is coding 16-bit games anymore, not even as a hobby or small project. It would be great if somebody did it for the Amiga a la Prince of Persia C64, like Mr Sid has > http://popc64.blogspot.com
