The ACA500 Compatibility Thread

[Astral]

Anyone tested the ACA500 on an Amiga 1000?

Jens, said do not try it. He will be working on A1000 one after A2000 one.

Anyone tested Blizzard IV SCSI Kit yet?

 

[roy_bates]

no mate,i dont have one anymore.

if i had the scsi,i might of tried it to bung another 128mb in there.just for giggles.

 

[mjnurney]

the scsi on the 060 is a no go ...but on a 30 it should work?

hang on i'll try again

SCSI doesn't crash now but the RAM allocation is wrong ...but it boots (no its not , wrong simm in it stupid)

 

[joekster]

after some quick tests...

DKB Cobra 030(flashed dkb to latest), *Almost* working - random guru's. But can boot to cli and run sysinfo. Gets as far as speed/mips, hangs on mflops...

Blizz 1240 seems to work with updated firmware and patched 040.lib

Amiga 1000 - dead black screen - no flashing lights on power-up. I suspect its the same issue as my csa-mmr (needs kick in rom?) No harm to card - still works when put back in a500

Rev 5 a500's seem incompatible. I'm 0 for 3 on them. Mine were all kick 1.3 ocs agnus.

 

[roy_bates]

why are trying to get to work in a 1000,when youve been told its not for the amiga 1000 and wont work?icard

 

[fitzsteve]

He he, I guess someone was going to try it

To be fair if it wasn't for people like joekster we'd still be sitting in a Cave rubbing two sticks together

I've had to opportunity to test a Power Computing Viper 1230 (the 8mb type like the MTEC 1230) and it does not work on my setup, (A500+/ACA500) the machine does not boot.

Steve, do you think (or have one to test) an a1200 memory expansion would work? I have a Hawk card with 8Mb sitting unused, would help to get the most out of whdload without an accelerator.

Hi Mate,

I haven't read of any reports to say they work or not so I can't say.

I'd be happy to test if you send it to me? (I don't have any here)

Steve.

ps. I will ask in the EAB thread.

Thanks, might do that, interested in the ACA500 but really don't need an accelerator, just the extra memory.

Did Jen not talk about releasing a 4Mb 'special' version at one point? I remember some reason about the extra 2Mb being fairly expensive that's why it wasn't added as standard. I think at the time it was suggested this would add £50 to the total price. Sounded good to me, 4mb on the card, but it would eat into ACA1200 sales so I can see why this wasn't a favored option!

He abandoned the idea of the 4mb version saying he couldn't make it for that price.

If you have an A500+ with 2mb chip Ram and use a physical 3.1 rom (i,e no Maprom) you can have 2mb chip & 2mb fast which is enough with a very light workbench to run a good selection of WHDLoad games if you use the ACA stand alone.

I asked at EAB if anyone has tried an A1200 trapdoor Ram board or even a Kipper2k Ram board.

I really think even with just the 2mb Ram as a stand alone version it's still worth getting

 

[roy_bates]

ive got a hawk and a rca120, both don't work.


i think jens said you could send the card back to have it reworked for 4mb,personally i would rather pay a little bit extra lads and put an aca in there instead.

 

[fitzsteve]

Even with 4mb?

 

[roy_bates]

no mate,no setting works on either.

if you still want to try ,go for it.it wont hurt to try.

Hi Roy, not to worry I just had a reply from Jens himself at EAB:


Me:

Has anyone tried a an 4/8mb A1200 trapdoor ram upgrade with the ACA500?

Or maybe one of Kipper2k's 8mb upgrades?

Jens:

None of them will work, because the A1200 slot on the ACA500 is meant to provide an interface to talk to the A500, but it can't be used "the other way round". If you want that, then the 68EC000 CPU would have to "talk 68020" through that bus, and that's about as much logic requirement as a full memory controller.

Jens

 

[roy_bates]

cheers steve


i was just going through a box full of old cards.

if it needs to talk to a card with a cpu on board say anything over a 020 i might have a couple more to look at.

Unofficially it appears to work with some A1000s, older models with daughterboard may unstable, sometimes it works, sometimes it does not and it can hang quite quickly.

You did connect it correctly? There are mysterious rumors that say A1000 slot is up-side down. It is totally incorrect, never ever connect any expansions (A500 or not) to A1000 slot up-side down!!

ACA500 does not need KS ROM, it will work without physical ROM chip.

Thanks chaps, that's that then! For me better to opt for something else.

 

[joekster]

My a1000's have the daughterboard (ntsc). I've never had good luck with them: csa-mmr doesn't work, adspeed doesn't work, but trr saphire 020/881 does work... Also mixed luck with zorro-2 cards with the tom thul adapter as well...

Anyways, i do have the aca500 connecter properly (front-to-back, but NOT bottom-to-top).

I'll try pulling the bootstrap roms - maybe they cause confusion?
I'll also try the two motherboard revisions (thikn I have a rev.6 and a rev.a)
