Look how fast my AMIGA is

Is this some kind of new 68k "Bochs" port running?
(If I remember right, DOSBox only supported 386?)

Yes this is PC-TASK.

APOLLO 68080 does provide some new features like little-endian support
and PC GFX format support.
Of course PC-Task does not know these new features.
So there is in theory great tuning potential to get x86 Emulation much faster.

wooo! i better start digging for my homeworld2 install disks, and a copy of win2k

that'd would be bonkers IF 1. PCtask or something got built to take full advantage of what a vamp can provide. win3.1 and solitare is already more than workable XD

486SX 55MHz, I had worse even running Windows 95 >:-) Who knows, maybe I could get Win 2000 and Office 2003 running :-) or better some really light Linux.

Homeworld 1 system requirements;
 
  Windows 95, NT 4.0, 98
  Processor (CPU)  Intel Pentium II 233 MHz 
  System memory (RAM)  32 MB 
  Hard disk drive (HDD)  80 MB 
  Video card (GPU)  4 MB of VRAM
  DirectX 6.1 compatible
 
Ofcourse, why run it on Amiga when it runs perfectly on Windows ;) But would be neat. 1 step closer to "only system you need" territory.

Some optimized V4 PC Task could do most of it, if game can run on 486 code. RAM and VRAM requirements are kind of "done" if they dont mean 3D card. If not, wait for V6 Vamp with some 3D chip

It's weird, I have a retail version of Dir Work 2 by Chris Hames which also came with his other program PC Task and up until now I had never ever tried it. Might actually give it a go. My version is 2.0 but I see v4.4 is freely available so will have a look at that.

Is there a native FPGA x86 implementation available for comparison?

Curious to see the type of performance that could be achieved.

Software optimization could be done on PC-Task.
All Vampires would equally benefit from this - not only V4.

With little Software tweaking on PS-Task "High end 468 performance" is a realistic goal for the Vamp - this would allow running many DOS games with good speed.

Most of DOS era games do run on high end 486 and quite a lot of productivity software too. Tuning it from current 55MHz level to 66-100 (DX2-DX4) area would do the magic.

Of course an issue is sound...

Unless Iím mistaken , sound blaster isnít included in pctask ? I forget if beeper is?

Yes, from v3 manual
  --------------------
  "The Sound option emulates basic PC sound. This is equivalent to the
  motherboard sound present on most real PCs and is intended for simple beeps.
  It does not emulate SoundBlaster or other PC sound cards."

  -----------------

  Back to Ser Clives Spectrum/QL style sounds :-)
 
  Well,DOSBox can emulate SB, can we steal some code?
 
  Other source could be some "PC X" emulator I have never tried.

Looks like it's fairly comprehensive but not particularly fast. Should at least outperform software emulation running on a reimplementation of a CPU.

Maybe Gunnar will give us his take on the theoretical performance.

from What Gunnar's said so far, the vamp already provides support for little endian in hardware. PC-Task effectively needs to be re-compiled for this, and any potential enhancements AMMX can bring to the table as well. so the vamp is good and done, but the software is good, but can be made better? only downside is if there was a vamp specific version of PC-Task, it would be incompatible with real 68k hardware...

that's my understanding anyway.

Two comments.
 
A) Adding a hardware 486 in an FPGA would mean adding something like a 2nd VAMP. This means you have to pay $$$ for hardware.
Are you advocation people shall pay another $300 for a new FPGA board?

 
B) APOLLO is technically miles more advanced than a 486.
And Apollo is clock by clock much much more powerful.
Lets as rough estimate say Apollo is 3 times faster than a 80MHz 486
Of course the emulation will cause a lost of performance.
 
The point now is how much can the lost minimized.
If you assume a reasonable tweaked emulation code, then outrunning a real 486 should be no problem for APOLLO.
 
Spending $$$ on a new FPGA card to run x486 seems to me like stupid idea if with software emulation you could get faster than x486 performance.

A rough estimation would be something between a top knotch overclocked 486 and a low end Pentium

That would be awesome because it is where DOS retrogaming gives it's best.
Of course if Soundblaster emulation can be stuffed in it would be even better

Nooo... I'm just curious to hear your thoughts on the type of performance that could be attained through an optimized FPGA implementation of x86.
