Hey, I know its not software...

I'm looking at designing a 'true' 16 bit computer.
The goal is to have full 16x for each aspect of the design; allowing 16 for video, 16 for ram etc..

Where as the Commodore 64 has 8 bits for video as its shared with the rest of the system.

I am looking to see if anyone has done this or has dealt with this before.

Cheers.

It sounds to me like you’re basically describing all of the 68000 and 80286 computers.

Is there something different you have in mind, compared to something like the Amiga, Apple IIGS, or Atari ST?

I like the 16/32 bit in the 68k, I'm not sure if it is the way I want to go though.

I prefer the simplicity of a Commodore 64 design though.

I'm still confused about what you mean by

"The goal is to have full 16x for each aspect of the design; allowing 16 for video, 16 for ram etc.."

Are you talking about having separate addressable memory banks for the CPU and the GPU? So the video chip has its own memory not directly accessible by the CPU?

I prefer the simplicity of a Commodore 64 design though.
There's something to be said for that design, although you can build a much simpler machine with modern CPUs. All of the complicated banking logic needed to make a Commodore-style machine work is unnecessary with a 16 or 32-bit CPU.
