Title: a1200 accelerators
Post by: lekgroda on October 25, 2012, 09:10:11 PM

Hi all!

Looking at the a1200 accelerators on amigakit
http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=43&products_id=1100
and
http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=43&products_id=1113

wondering.. does the 020 card make the Amiga faster? Is'nt 16Mhz the standard speed? Or will it just give me more mem?

Does the 030 card have any other advantages over 020 besides the speed?


Cheers!

The ACA1220 will undoubtly make your stock A1200 faster:

Standard A1200 = 1.37 SysInfo Mips (aprox)
A1200 + ACA1220 = 3.48 SysInfo Mips (aprox)

StandardA1200 = 2MB of chip ram
A1200 + ACA1220 = 2MB of chip ram + 128MB of fastmem

Not only the mips (cpu) is important regarding speed, because with that much fastmem on the ACA1220 you can probably put all your system structures on fast memory (your entire System might also fit there), and you will get this way an added bonus in improved performance.

ACA1232 vs ACA1220 issue: Besides speed and MMU (this last one useful on some rare ocassions), I guess there isn´t something else that makes the ACA1232 stand above the ACA1220.

Thank you for clearing that out for me Gulliver!


Is it hard to put system in fastmem?

Amiga 1200 is 14mhz as standard, so it's a marginal increase in speed.
 
However the 68EC020 in the Amiga 1200 can't access more than 16mb of ram (and you lose some of that to rom and custom chip registers).
 
Just adding fast ram will make an A1200 faster, as it can't run full speed with only chip ram. The extra 2mhz you might not notice, but without that 68020, you can't have 128mb of ram.
 
The 030 is quicker, has an MMU and can map the rom into ram (which also makes it quicker). It's more expensive, but if you want the speed then it's worth it.

I'd go solely for the 030 option, no question.

Thanks psxphill !

Bamiga2002, I will have to sleep on it :) hehe


By the way
Does any of these cards effect the graphics in any way? Like being able to run higher resolution?

The only question you have to ask yourself is: What will I use it for? If you're only interested in WHDLoad games, then the ACA 1220 is perfectly fine, no need to spend almost 50 pounds more. If you want to use Workbench and applications that require some CPU speed, then go for the ACA 1232.

No higher resolutions I'm afraid.

All right, thank you, good to know. Games are the main thing ..
Other software and work will have to wait until the netbook is relased.

I ordered an ACA-1232 this week on amikit. :banana:
Can't wait, to try this on the amiga.

Working out which model to get is always a problem

We have updated the product description with SysInfo, Bustest and AIBB screen shots here:

Those numbers are looking good.
A bit slower than an A3000/25Mhz with Integer (which you'd expect with the slower speed), but not much.
And faster graphics performance...

All in all, that's a nice looking little card..

If I didn't have my ACA1230/28 (Thanx Amigakit!!!), I'd probably pull the trigger.  ;-)

Now, I have an 030 (EC tho, so no MMU), so I agree an 030 is nicer. ;-)

But won't the 1220 be able to map the ROM into RAM using ACATUNE?
That feature doesn't need an MMU, so it should (I think?) also work with the 1220.....

Do you have any idea, when your stock arrives?
It's bin delayed for thee times now, i believe...
On the moment it say's overdue..

Both the ACA 1232 (http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=1113) and ACA 1220 (http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=1100) are now in stock- thank you to everyone who preordered from us, we will now get to work and ship their package out :-)

Any plans for a version with a 68882 FPU?  An 030 really doesn't speed up a Mac emulation much without the FPU.

Anyone know of an accelerator for the A1200 with an 030/68882 or 040?

Hi Jim,

Sorry- there are no plans by the manufacturer to introduce FPU support.

Title: Re: a1200 accelerators
Post by: desiv on October 30, 2012, 09:03:46 PM

I've actually heard some people say that you can add an FPU to the 1200.
There's a spot on the board, and supposedly, as long as your accelerator doesn't have one to conflict.

I'm not sure what all is involved other than soldering in a socket (and a clock source?), but for technical people, it should be doable I would think..
