Amiga 2000 & OS Version Recommendation

Running 3.9 on a GVP combo 030/40 with 12MB and PicIV card and runs great but would suggest 2MB chip to go with it. I notice a difference.

GVP Combo cards can be picky. My 030/40 card will handle 16MB on board, after that nothing on Zorro. If I remove 1 Mem to 12MB it will take 4 MB on Zorro with room for auto config. A Tekmagic2060 will take anything even with 128MB on board. Depends on card.

The GVP has 5 MB of 32-bit RAM.  The Supra has 6 MB but I had to set it back to 4 MB because the VA2000 needed 2 MB of address space.  So, if there is a max of 8 MB in the Zorro II address space, is the GVP doing 2 MB of Zorro II address space RAM, Supra doing 4 MB, the VA2000 taking up the other 2 MB and then the GVP doing the remaining 3 MB somewhere else?  Is there a way to put all GVP RAM "somewhere else" so I can set the Supra back to 6 MB?

I think I would try 9MB on the GVP and remove the Supra. You will probably see a jump in performance.

@madgrizzle,

Your combo card has a limit, it is 16MB of total memory. With a total of 13 MB on the card you only have 3 MB of room left on the Zorro bus! If you plan on a graphics card add that to the bus, If a 2MB Card you will Have 1MB left. With a 4MB Graphic card you would have to do with 9MB or change the soldered Mem to 4MB and leave out 1 stick of 4MB. Or if not adding any card you can change the soldered mem to 4MB, fill the GVP and have 16MB.

If the GVP card puts its memory in the 32-bit address space (I assume it does, most do), then this information is incorrect.

Your actual limits are closer to 128MB (32-bit RAM), 8MB (16-bit RAM), and 2MB of chip. If you later add a graphics card (2MB or 4MB) that will come out of the 16-bit (Zorro 2) address space.

Of course YMMV, bases on any limitations of your particular accelerator. If it maxes out at 16MB of 32-bit RAM, then adjust accordingly.

I have the 030/40 one with 4 MB on board. If I load it to 16MB and add anything to Zorro it either will not boot, have glitchy operation or things will just not show up. I must remove 4 MB to put anything in Zorro. There was a post from a GVP engineer not too long ago about this on this site or the other but can't find it yet to point to it. Something about limited address space on old cards.

@Oldsmobile_Mike,

I loved the way the TEK2060 made my A2000 fly. I think it's time for a Vampire now that Gold Core 3 is going to be released!

Well, I booted the Amiga and installed OS3.9 and boingbags 1-4 with 13 MB in the GVP, 4 MB in the Supra and the VA2000 taking up 4MB of address space (which apparently can be changed to 2 MB if needed per the developer).  I had no problems with it running all night, but I'm not sure I really taxed the memory.. All I had time to do was bring up aminet.net on AWeb after I got the plipbox working.  I'll see if I can max it out tonight to see what happens.  At the worst, I can set the VA2000 to 2 MB and pull the Supra leaving 13 MB on the GVP.

Let me know how this goes. Maybe I need the newer ROM in my card or something else is wrong...

[QuikSanz]

Hmm, Looks like there is a problem with my card or setup!

A tid bit off topic. but, here goes:
Is there an easy or usable tcp/ip stack for os1.3 or os2.1?
