Do you think it is possible to use Vampire V1200 with ACA500+ on Amiga 500?

Why do you want to do that? For a500 there's the vampire 500v2+ that's a beautiful card, it's cheaper than v1200 and is perfectly build to fit an a500..

i echo Stefano's question:  why??????
 
  The V500 V2 is cheaper than the V1200 and is made to work specically in the A500.  This makes no sense at all.  None.  Zero.

  No. Vamp must be only accel card.
 
  V1200 has diffent connector and customized FPGA for A1200 board.

  If you wish improved Vamp, wait for V4 for A500.

The ACA500+ has an A1200 style edge connector and even a BPPC and BVision have been tested and work with this card.

Reasons for using the V1200 with an ACA500+ could be as follows.

1 The user already has the AC500+.

2 You don't need to open the A500 to install a Vampire card.

3 The ACA500+ has 2 CF card slots for additional storage or backup.

4 The ACA500+ has an A1200 style clock port which is handy if you want to plug a Prisma card in.

5 Because you can.  Assuming the combo works.

  If its full accel card
  EXTERNAL LINK 
  He is faced with choice of one of the cards.
  Replacing fast 00 with 080?
 
  Or Standalone.

  Standalone only :)

  Really sad we only have one CF and MicroSD.

  I am not sure can this be brought to A500 some other way, but its a dirty hack and prefer Amigas with clockport built in, if would ever go that lane.

  I would not say that twice. You can buy and try, but fat chances that Vamp will work over existing card connected to real expansion slot :) Or it might? Whats next plugging Mediator and PCI/Zorro card that has A1200 style expansion and adding Vamp?
 
  Such approaches if they work in the end can face some bottlenecks that would result in lower results.If it happens, dont blame the Vamp. Sufficient power needs to be provided and stability of all components in chain.

ACA maker says:

It is guaranteed to work with our ACA1220, ACA1221(ec), ACA1232 and ACA1233(n) models. Our older ACA1230 accelerators are not supported. We will therefore only answer support questions about ACA1220, ACA1221(ec), ACA1232 and ACA1233(n) accelerators.

I would NOT assume it works.

Again, Vampire 500 can't work with other accelerators in parallel or with onboard CPU (MC68000) because V500 card does not support bus arbitration logic.

Why do you speak on behalf of the team all the time, and spreading fudd.
Just let the people answer who know about this stuff...

Nobody was talking about using V500, "with other accelerators in parallel" or otherwise.

The talk is about V1200 on the ACA500. ACA500 isn't an accelerator in this context. It's an adapter between A500 and A1200 edge connectors, so that A1200 accelerators work on A500.

It's compatibility is very good. With ACA500 you can use blizzardPPC, Bvision etc on A500 and A1000. So it's reasonable to wonder if Vampire 1200 would also work.

Other built in features of ACA500 aren't involved or relevant in this context, they're not used.

Of course, just using V500 in the first place is cheaper. But it's a scientific curiosity, nothing more.

But the ACA500 has some 020 on it so I guess that might need the aforementioned bus arbitration.

ACA500 (+) doesn't have a 020 processor, only 68000 and cards from Amiga 1200 are connected to it. So it's about connecting the V1200 to ACA500 (+) and checking if it will work. In the amiga 1200 we also have a processor and we will not desolder it by connecting the V1200.

@Kyle Blake
It is not true that ACA500 is not used in the process when another card is added to it. When you add one CPU and there is another in the system, or several, there is lot of things that needs to be done to make system work. In that mentioned setup you would have 3 CPU total who would drive the bus same time and probably destroy complete system. How is this done on ACA cards we don't know, it is some type of bus arbitration logic. Since I don't want to have 1m long pile of cards connected on the left, running out from my case, touching house near me, I won't even test this.

Do what you want. But others are still curious.

Well, IT IS an interesting question, but even if it works, it's utterly pointless, imho. It's like waiting for tragedy to happen. :)

I have ACA 500+, and pretty happy with it, but I plan on buying standalone, once I have funds, and that way, I will basically have both low/end and hi/end Amiga. What else could someone want? :)

Some Amigans like their machines "Pimped out".....
  thats a good question, can Vampire operate in a supped-up Amiga ..??? :):):)

My bad, that was just for Boban K..  if Vamp is the only accelerator so be it, that won't be a lost...

Oh, Dark Elf is here too, cool :) Such positive guys are most certainly welcome!
