What is the real power of Akiko chip in cd32 ?

c2p Gloom 1x1 256 colors

Question, what will be the result on SX32Pro 68030/50+fast+akiko?

I could try that, but I am just too lazy.

[kolla]

You can see that you never use the Amiga. You're just a collector.

Yeah, I "collected" the SX32 Pro back when it was new, from DCE. I use it a whole lot, but not for games (SX32 Pro was not made for gaming), and I don't have Gloom.

[kolla]

The SX32 was bought for running Linux, believe it or not. It was in 1996 or 1997, and for a period it was used for OpenBSD too.

[kolla]

Make sense to me, although I would prefer NetBSD.

At the time, OpenBSD was to be considered a NetBSD distro, the kernel was identical on m68k

[kolla]

So, last night, since I was playing around with MuTools anyways, I also downloaded GloomC2P, here goes...

You can be productive using obsolete software, how efficient you are would be the real test.

Damn right. For example, I always keep FS-UAE around on my systems because of Deluxe Paint - it is a program I know how to use and how to get the results I want, trying to get used to so called modern paint programs just leaves me frustrated.

What I use the CD32/SX32 mostly for these days falls under tinkering, which I find quite satisfying in a therapeutic kind of way. I am just done replacing all spinning IDE drives in all systems with either SD-adapters or mSATA adapters, and well on my way to build RaspberryPi systems inside all the Amiga computers, to provide various services (wifi, 464XLAT, resolver, ntp, smb), so for the SX32 I plan to build in a PlipBox, that will be plugged directly into a RPi mounted on the 2.5" disk area of the SX32, which is empty after I replaced IDE drive with an SD adapter and card

[kolla]

It's true power lies in its ability to generate forum discussions 23 years after it was released.  

Hah, yes. People still think it hides magic powers :laughing:

[kolla]

So, now the numbers are there for a 030@50MHz + akiko and everyone is totally unimpressed. Yeah, that's what I thought, lol

[kolla]

I think they only make sense if you can compare them to basic a1200 or basic a1200 + 030.

Or the very same system, only using the 68030 instead of the akiko:

Hi Pat
I did mean CD32 14mhz + Fast Ram.

My results are from CD32 50MHz 68030 + Fast RAM.

[kolla]

I guess sooner or later somebody will come up with a suitable accelerator

A1200 acc boards are shrinking, there are AFAIK no technical obstacles preventing something similar as ACA500 for CD32, "ACA32" if you like, that would let you use A1200 acc boards on CD32.

[kolla]

There is plenty of space in a CD32, really, more than enough for both a card, cooling ribs and a fan.

It's like a garage in there!

Open CD32 with ACA1221 and RPi 2B, just for size comparison...

The biggest obstacle I can see to an internal accelerator card for the CD32 is that the cpu is surface mounted.

Er... guess how the SX32 Pro is connected :p
