Title: ACA1231/42 Accelerator card and possible PCMCIA problem
Post by: outrun78 on May 05, 2012, 06:34:42 PM
Hi All
I was wondering if any users on here have had any problems with the ACA1231/42 accelerator card and the PCMCIA port on an A1200?  
I used to have a Turbo 1230LC card which with the 4MB ram worked okay with my Archos Overdrive CDROM, however whenever I placed the jumper to 8MB on my old card this knocked out the CDROM and i was aware that this was a problem with the accelerator itself. I changed the accelerator card recently to a brand new 64MB ACA1231/42 which i was assured was PCMCIA compatible, however I am still experiencing the same problem and of course on this new accelerator card I am unable to downgrade the memory as it is built in.
Is it likely to be the Archos Overdrive CDRom which is the problem, it has always been rather shaky in operation since i have had it?  Also as a replacement would you recommend the use of a IDE CD-Rom  as a way of solving the problem just in case the new accelerator card is causing a problem with the PCMCIA port??

Mine is the 030/56 ACA but for what its worth, ive had no pcmcia issues using either wireless or compact flash adapters.

I had a PCMCIA 2.5" Overdrive HD version. The HD won't show when I was using a Blizzard 1230 IV. It could have a compatiblity issue with your card.

I've never had any problems and regulary use my pcmcia WIFI card for networking. Not sure what could be causing your problems....may be worth raising a ticket with Vesalia.

Not me (ACA1230/28) and not that I've heard..

Not really the accelerator's problem.   Kickstart 3.1 intentionally disables the PCMCIA slot if RAM at a certain address range is over 4M to prevent possible conflicts.

It is.  The ACA series doesn't use the conflicting memory space...

You can disable the fast RAM I think (is there an ACATUNE option for that?) or possibly use a degrader software to do that, but it's unlikely to help.  This likely isn't a PCMCIA / RAM conflict, as mentioned above.

I have just acquired a Surf Squirrel PCMCIA SCSI card with a CDRom attached and that works with my ACA1230.

I'm wondering if the Archos driver has some timing conflicts with the ACA.
There are a lot of options in the ACATUNE program; one of those might help with compatibility...
