@V8

Users do not care about ISA. Most computer users today use devices and not even know what CPU is used. Mac users also already have changed from 68k to PPC to X86/AMD64 and now to ARM. They use Apples... Finally users are only interested in the result, what do I get for the money. If the CPU needs 1 command or 5 commands to do something and if something is more efficient per instruction than another CPU is completely irrelevant. Discussions about ISA is retro

@Hypex

"PC" was even used in C128 ads

Example the ad on this page:

You speak sense and with the PPC worship cult in attendance that is not a given!

THEA500 Mini and the PiStorm32 have convinced me that for the majority, the experience with Arm based emulation hidden underneath either Classic Amigas (accelerators) or Amiga themed branded hardware to evoke the original experience is more than good enough! I like owning temperamental Classic 68k hardware but not everyone will and that's fine to grow the retro market and undermine the scalpers!

As long as Amiga is only hobby cpu is important.
Amiga has to be something different than work.

olaf szonwejs provide working mui clone on x86 or arm or get lost.

@BigD

pwcamina keeps talking nonsense. And who cares about MUI? Me not

I think the retro market will grow in future

And I look forward on combining aros components and desktop with linux, That offers something new. We will see what will happen

You say "Amiga has to be something different than work", yet immediately go on to demand someone works on it

Exactly! And in this configuration, you can perform operations on 32 pixels with a single longword.

For AGA, Commodore didn't include a chunky pixel raster to interpret chunky pixel data format from RAM.

If AGA has chunky pixel raster mode, the 68EC020 @ 14 Mhz CPU is still gimped by the shared memory architecture.

Alice needs to be redesigned for a 68020 CPU since Alice still has 68000's 2-cycle memory access pattern. 68020 @ 14 Mhz has hardware barrel instruction that is gimped by Alice.

Commodore didn't have a proper graphics chipset designed for 14 Mhz 32-bit DRAM.

With a very fast CPU and Fast RAM, the AGA display adapter would be like an upper mid-range fast 16-bit VGA+ card while ET4000AX (16-bit ISA) is faster.

For my A1200, I have my Raspberry Pi 4 Model B has arrived and I'm waiting for the PiStorm32 Lite delivery.

How much was the RPi 4 Model B? They seem hard to get at the moment!

Why did Commodore stick a 1984 CPU (68020) in a 1992 machine (A1200). That’s just lame! It could have had a least a 68030 which was a 1987 CPU. Still created 5 years before the A1200.

Yep. As with most things, follow the money.
If the A1200 was going to retail for $599, then the cost of produced hardware had to be below $250 per unit in volumes of 100k+

Maybe they considered an EC030@25MHz, but just like a film editor trying to fit their story into 120min runtime, some good ideas end up on the cutting room floor.

Given the lack of profitability in 1993, I would say that C= did not get the cost below $250, even with the EC020@14MHz.

Which goes to show just how much they sucked at managing manufacturing and logistics.

There’s not much to benefit from an EC030 over an EC020, aside from how much fast ram one can add, and this was a time when having just 4MB of RAM was common, even on PC.

A1200 was not designed to last for decades, none of these systems were.

Many years ago I have Amiga with AGA.
It was interesting only if one forget about blitter and use it with cpu only.
But it made Amiga with AGA something like slower NG.
In this fake NG mode AGA was barely enough.
Not good enough but almost enough.

@Karlos

Amiga have to be either work or hobby.
If you want to use x86 or arm provide something decent
good enough to sell to people outside amiga community.
Or it should be hobby and stay on something other than x86 or arm.

@ppcamiga1

The RPi is built for industry plus hobby computer enthusiasts and that's Arm based so you make zero sense! Or are you saying the 'hobby' is making bespoke PPC computers for thousands of £s in a cottage industry?! Is it a hobby to build underperforming machines for the price point with chips that are unavailable and end of life? If so what a pointless hobby but I guess at least someone is passing the time whether we buy any computers or not!

I ask because they seem to be about £140 + p&p on ebay right now! Did you manage to get it any cheaper?

Amiga is a hobby. End of story. So anything goes.

The performance difference between 020 and 030 is insignificant at the same clockspeed. You might be able to craft some hand assembler that is able to leverage the miniscule data cache to get better performance relative to 020 but it's not going to be a lot. The 030 differentiates itself by having an onboard MMU (if you don't cheap out), which AmigaOS didn't really need and by clocking up to 50MHz. So, unless they were going to go to those clockspeeds, the 030 was pointless in a machine aimed at reducing cost.

Amiga has almost always used old cpus.
The Motorolla 68000 was released in 1979 for eg.

Commodore's Amiga was still much closer to current than any of the PPC clones though.
They can be up to over a decade old upon a machines release and ~1.5 decades old when it comes to performance.

Usage dictates what is a hobby or not, not architecture/ISA.
Probably %95+ of x86/x64 users are computer hobbyists.

Just because something isn't obsolete doesn't mean it's not suitable for a hobby.
There's more people that use modern gear for their hobbies than those that use retro/obsolete gear by a huge margin.
Some enjoy both modern and retro.
There's no absolutes, rights or wrongs.

Repeating something over, over and over again in spite of evidence in the real world doesn't make you correct. It just makes you an idiot and/or nutjob.
