Individual Computers - New accelerator cards for A600 & A1200

From what I could understand on Jens, it seems like you most likely will need the fix to get it to work, however there was no way to be sure (e.g. a particular board revision) until you have the accelerator installed in the Amiga. Don't know if it's 75% or 90% probability, but you should expect it. There are many people in this forum with the skills to apply the fix, so perhaps someone nearby will do it if it's needed and you can't do it yourself.

My A1200 1D4 was unstable with the ACA1232 so I did the timing fix and it seems quite stable now (been able to run 1½ hours without problems) but I will continue testing tomorrow as 1½ hours isn't enough to say for sure.

Unless it's changed from when I got my 1230, there was no way to tell.
It's not the same, even within the same revision MB.

So what we were being told was not to apply the timing fix UNLESS it didn't work.

I got my 1230, and lucked out. No fix needed...

I've had my 1200 running memtests with the ACA1232 for more than 5 hours in total now without any errors, so I can safely say that the timing fix was required for me as it would crash after just 10-20 mins without it. Now I just need to fix the remaining small errors that are in my A1200 like the graphics corruption and bad audio. At least it is stable, unlike my 600.

Oh, and I also need to find something useful to do with those 127 MB of fast memory (129 MB with SRAM card ). I think my biggest WHDLoad game uses about 10 MB..

Try Beneath a Steel Sky CD32 with speech. Needs app. 100 MB for preload.

Cool, will try that.

As far as i can tell, same here. I haven't used any "tests" to determine tho, all can just state that after hours with Settlers, Frontier elite, and K-240, it's been behaving as it's supposed to. I think i got a 1D4, and the ACA version is 1230/56

[supaduper]

Just to add to this guys fitted AmigaKits ACA1232 to my A1200 1D4 and no probs great stuff burned in after 8 hrs continuous work nicely, tried loading it with few AGA games and all perfect, great stuff! one happy Amigan and with INdi F/F what more can a miggy want? oh I know a USB subway, so get some in AK

[drohan]

Thanks all for your answers. Seems I have to wait until ACA1232 arrives and test.

Keep my fingers crossed as I am not an artist with the iron ;-)

ACA1232, RTC module (forgot to purchase battery though *facepalm*) and KS3.1 roms just arrived.
Everything works like a charm (fixed 1.D4 mobo).
Now it's time to try out Beneath a Steel Sky CD32.

[supaduper]

Update sorry guys my ACA1232 started crashing but all fixed ! right used game `Mad Professor Mariati `as crash test. It would not play this game as some poster previous had mentioned( and yes it crashed after intro sound crap aswell),so did the timing fix mobo out resistors removed(E123c and E125c) and Bingo! Yatzi!The mad Pro was Madder than ever
All done so can confirm will prob need fix if not already done but if I can do it in under 20mins then anyone can my Mobo is 1D4.

Hi,

I have an Amiga 600 2D June Bug. It came with 37.299 Kickstart originally (Which I replaced as a kid but I still have the chip so sure). Apparently this combination should nt exist.

Anyhow I brought an ACA 620 I fitted it and it works. I havent tested it for long periods of time though.

I dont really get a few of the options. I havent downloaded ACA tool yet.

When I boot from my hardrive (waiting to get flash card running). It says I have ~2MB ~10MB fast.

When I boot from disk drive to PCMCIA card (to some kind of compact flash version of workbench) it says 2MB chip. 4MB fast and 6MB other RAM in the title bar.

I thought I needed to use ACA tune to get the other 6MB but I seem to have them off the bat.

Also can I use the options for ACA tune listed on here->
http://amigakit.leamancomputing.com/...oducts_id=1003

anyone any ideas of the best options for a ACA 620 ?

Also I see a 25Mhz ACA 1220 has just appeared on amiga kit. is a 25Mhz ACA 620 just round the corner ?

[johnim]

hi the aca620 was to cut price on previous aca630 so i don't know if Jens will make a faster 1

When you boot without ACAtune it should give you 5 MB fast mem (4MB 'normal' fast mem and 1MB at $c00000 like A500 ranger memory). The remaining 6.3 MB can be added using ACAtune (-maxmem option).

Start out with this commandline in startup-sequence:
dh0:c/acatune -maprom <kickfile> -maxmem >nil:

If I boot with a CF card in the PCMCIA bus using maprom it will mount it as 4 MB system memory which will show as 9 MB total fast mem before using ACAtune, but these last 4 MB are not valid memory, so maybe this is what you have? Try booting from IDE without anything in the PCMCIA slot.

ok will do cheers for info

Hello Jens,

Here is another one

I have an ACA 1231 and an ACA 620. The 1231 has been working without any problems until now, whdload runs perfect with it.

The ACA 620 is the complete opposite of that.
9 out of 10 whdload games don't work. The A600 always crashes after a few second of playing which makes the card unuseable for whdload.
I took the same whdload settings as for the ACA 1231, max transfer settings of the cf card are also correct.

What could be the reason for this ?
The A600 is Rev 1.5

hi Mr.EE

are you trying AGA games on your A600

Seems like you have a PCMCIA S-Ram card installed. This will not work properly. Please remove it for proper operation with the ACA620. The ACA620 is PCMCIA-friendly by means of IO cards (for example networking), but not S-Ram cards.

Mr.EE: Please wait for the results of demolition's test. I've sent him a modified ACA620 that will most likely fix the problems he reported. If it does, I'll exchange yours as well and apply the fix as a precaution to all other accelerators.

Did you see this thread regarding the ACA620 and the PCMCIA port? Maprom seems to affect something with the PCMCIA port.

You should have told me that much earlier - you've got my eMail, and you know that I don't scan forums for support questions. Support goes through the reseller, and in rare cases (like yours) can be done directly. Support is NEVER done in a forum.

I'm fully aware of that. I only provided the link since you were already talking about compatibility with SRAM cards, so I thought the info might be relevant since it's not just SRAM cards that can be a problem.
