It is perfect, you does fine! Far better to be based on a stable design. The bench results are already a dream.

New core,

Is this officially the fastest Amiga1200?

Nice! Looking forward to the V1200.

I think its time to pick up the phone and call Nic Wilson ;-)

<jealousy>Yes.  How much do you want for it?</jealousy>

Hurry up and take my money!!!!!

hello team, few simple questions please

- how much it will cost about the card V3 for A1200 ? about € 370,00 as V2 for A500 and A600 ,or little more ? (400,00) or much more (500,00 ?)

- Will be possibile to use the V3 for A1200 with Mediator PCI elbox to play warp3d games with Voodoo3 in 68k mode and in PPC mode with PPC PCI cards (sonnet project) ? or not compatibile ?

- Will be compatible the V3 for A1200 with Indivision MK2 of icomp ?

- Will be possibile at the end of 2019 a V4 for A1200 and one for A4000 with FPGA Cyclone 5 or better ?

thanks

The V2 and V2+ are 300€ at EXTERNAL LINK (299€ should sold a million ^^). I imagine the same design for A1200 will have a close target price, that will be fantastic because it will not split de community about softwares limitations. For myself, I'm not interrested about a Cyclone 5 or better version if the price increase too much with the power. This hardware is already great compared to the existing expansions. V4 is perfect for a standalone solution in my opinion..

@Richard
      Cyclone 5 is not so much about "power" as it is about "More space on the FPGA". If the hardware FPU was a tight fit in the Cyclone III then the upcoming "GPU" will be even harder - or maybe completely impossible? :-) (Whereas the Cyclone V gives plenty of space to add features).
      Don't know what sources they have but, (as a reference) from e.g. Mouser Electronics, the Cyclon 5 E is about ~90 euro.
      But remember, end cost of card is probably more development and labor/assembly time than component cost (even though you have FPGA, RAM chips, hard to find connector, PCB).
      Majsta does this full time, he needs to put bread on the table like the rest of us.
      Anyway, IMO I think > 350~euro is still a fair price for what it does..

@Daniel, as I know the Cyclone V allow a higher clock and support fastest external memory ... Understand that more space = more features = more power too. (as you said, an uncomming GPU ...)
   
Next, I think that is good to have the same design for all the Amiga range of computers to not have gaps with the different models to be able to offer the same programs quality for all.
   
Currently, I do not want to dev any games project on a "never finished" hardware. I definitively not want to buy a Vampire for SysInfo or AIBB ... It is an useless bid for power. It is why I'm really interrested if the A1200 version is close to the A500/A600 version.

Why is the ChipSpeed so slow?

Likely because it's using the actual chipram on the A1200?

@Michael AMike Yeah it needs some more work. I did improve it but it is not there yet. Somehow reply from Gayle is too slow now but I have some ideas how to fix that.

just out of curiosity, what's the FPGA's cpu bus connection back to the A1200 board itself? 16/24/32bit?

just the V2(+) only had to interface to the OG 16bit 68000, where as the A1200's based on the 24bit EC020. do you have to take all of the CPU bus at power on's "CPU bus grant request", as if I've been made aware correctly, the custom chips themselves are only accessible on a 16bit cycle anyway?

please excuse my poor question phrasing, getting over illness/tiredness/overexcitement about this project in general.

Address bus is nearly the same as on MC68K but data is 32bit. Bus arbitration is very simple 2-wire like on MC68K.
BR <= '0';
if BG = '0' and As ='1' and Dsack = "11" then
.
.
.
Depending on the type of transfer long,word or byte we decide what to take from the bus or what to write. So it depends on A1,A0, Siz1,Siz0,Dsack1 and Dsack0 so it is lot more complex than on MC68K. As said before this needs some more work to get perfect timings and gain better performance.

Hoping that with new hardware, finally more software will come. At the moment games and tools seems to appear only here in this forum, Wiki is outdated on many places and programmers are leaving the Vampire again.

  You forgot to mention that the sky is falling.
 
  On matters, which actually relate to this thread, I am thoroughly looking forward to the arrival of the V1200.  The A1200 was a true A500 successor and very much deserving of the Vampire Accelerator.  Nice work guys!

are there any news on the v1200 ?
It's been a while since the last update and I can hardly wait to see the v1200 become reality!
