What nm process used for Agnus/Denise/Paula etc?

[freqmax]

Which nm manufacturing process has been used to produce the Agnus/Denise/Paula chips in Amiga 500..?

And what transistor count and die size is it?

(The scanning thread seems to went about something else)

I would guess 2000nm to 1500nm for process... And I doubt any Amiga custom chips has more than 30,000 transistors.

Jut looked up MOS (later CSG) and I think they were stuck on some pretty old technology... My guess is that the Amiga chips are probably even 3000nm (3micron)...

I wonder if a digital camera can get enough detail from a 1.5 µm chip to deduce logic?

Wasn't some parts of AGA fabbed by HP? Presumably because CSG couldn't fab what was required.

Meet...

Lisa.

I think you are right, CSG's fabs just weren't up to the task, Lisa might even have been some standard HP mixed mode ULA (now there's a thought for another thread!;) )...

I also seem to remember Jay Miner expressing surprise in an interview in the early 90s that most of AGA was still fabed on the original process that they used back in the mid 80s...

I wonder what nm process the AGA chipset might have used..

I remember reading somewhere that the original 3 magic chips were supposed to be one big chip, but the fab tech of the time was not up to doing it all on one die.

If anyone knows the transistor count and die size. It might be possible to do some estimation.

Anyone else remember that aga was to be intergrated into the cpu die? I remember a few interviews with key figures (David Pleasance or Lou Egbert perhaps, it was a while ago) in amiga magazines back in the day talking about it and I was curious as to how they'd planned to do it being that they had no license for 680x0, nor did they have the facilities to do it even if they did.

Both forward thinking and stuck in the past at the time (ie. intergration of custom hardware in a cpu die at the time was pretty forward thinking, but sticking with aga was kinda crazy).

@fishy_fiz: I think you are confusing AGA with Hombre. AGA was never much more than an ECS upgrade. Hombre was supposed to have a PA-RISC core integrated in the chipset.

I already pointed out that it would be either 3000nm or 1500nm....

Nah, it was definately aga. I remember arguing with my brother about the advantages it would provide. He was of the opinion it was interesting, albiet a little silly, and I was such a hardcore amiga guy, and too young and naive that I believed aga was the bees knees (even though this was post a1200/a4k/etc.).

Somewhere in the back of my head I seem to remember that C= had actually got a licence for 680x0. I remember some passed-on posting from CIX about a new cost-reduced model that never saw the day of light.
