FPGA Replay Board

[freqmax]

What has X client/server to do with this??

[freqmax]

16-bits is actually quite ok.

[freqmax]

What's up with the DRAM controller?

Is the FPGA wired differently on the newer boards such that cores can't binary used anywhere?

[freqmax]

Buy some components, Learn electronics, Learn CAD, place PCB order, play with synthesis and C-code, Cool-card-under-green-tree!

(I think the hard part is signal integrity and DDR-RAM interfacing and the expense of multilayer board with BGA)

[freqmax]

Maybe one could add something to the verilog code to handle the DB9 atari style ports as PS/2 ones with a suitable connector adapter?

[freqmax]

no, just static input delay is not good enough for normal device variation.

What kind of input delay do you mean?

I'd rather have Megadrive controllers work as a CD32 gamepads, but it's good to have options.

What makes it impossible to have both possibilities using the same hardware ?

[freqmax]

Plug and PRAY!

Plz, add some option to force the setting.

[freqmax]

PCI etc.. = more $$ and also more EMC issues.

Just a suggestion.. put a list in the order of first to get board online. Then less people need ask for the status

[freqmax]

Amount of chip/fast RAM is just a matter of hardware description language (HDL) settings. And can be changed at will at boot. Perhaps while running too. The third option is RAM disc.

As for features. There is a slot that makes it possible to add various boards. YOU can even make your own if you wish. You don't have to rely on MikeJ for that. Also given a multi layer board every extra surface area costs premium.

One option for a daughter board may be an extra FPGA which could then implement hard to get MC68060. And non-existent AAA.

(and I agree fully with MikeJ last answer regarding PCI)

[freqmax]

Sources to that claim?

[freqmax]

If there's a LED output, it's a piece of cake to fix.

[freqmax]

You have to wait until next year for anything to happen!

[freqmax]

In the other end of Ethernet you can place a terabyte fileserver far away so you don't have to be bothered by it's noise but still can enjoy the file space

[freqmax]

Idea.. use the daughterboard with special FPGA setup to test and separate the fakes from the real thing?

[freqmax]

There is no "emulation"..

Biggest reason why I will never own Minimig because it is completely burned in my brain and will not change is nothing more than UAE running on ARM. However, FPGA is completely custom based, real chipset, in my opinion the new and latest Amiga upgrade had Commodore continued in the line of 68k Amiga. Is why I did preorder for FPGA and did not spend a dime buying Minimig even if it is out already for sale.

Minimig is a re-implemention in FPGA just as MikeJ's FPGA Replay. The difference is that the CPU is in ASIC and RAM is less etc.

A cobbled together A1200 gets to use 128MB (possibly 256MB) Radeon gfx cards which there is no way to do with the Replay.

The FPGA can interface directly to PCI 33/32 and other interfaces can be handled by added suitable transceiver chip or upgrading FPGA with onboard ones (Rocketport etc).

If you don't like your SCSI hard drive you are allowed to buy a new quiet, cool, fast SCSI hard disk for your old Amiga.  Or you could just get a cheap silent slow SD card like a lot of ppl do.  Or you could use a new slow IDE drive.

Your SCSI controller is likely faster and smoother than whatever Replay has to offer. (Which I cannot remember right now.)

Complaining about SCSI is a really silly thing to do.

The present drives are almost all either horrible expensive SAS drives which will not interface with Amiga or S-ATA ones that will neither. So you will still need to make do with the SCSI-1 SE narrow stuff that were common with Amiga. Present flashmemory (SD) will beat ordinary Amiga SCSI hardware on Mbyte/s basis.

The reason I bought SCSI is because it has a sound electrical interface, clean hardware API with well defined orthogonal commands, reliable etc. Something P-ATA never managed. Infact S-ATA drives are still second rate when it comes to build quality that's why SAS drives are more expensive. BUT with RAID or ZFS this issue is negated..
