whats this card

[lordnicon]

i have a2620 but i cant see any ram on it but i don't know
a2091
a2058

hummm it new to amiga so i don't know whats diffrent with the OS

[Ilwrath]

EDIT the chips at the top
"D42274V-10
9229FUO29
NEC JAPAN" and there is 16 each side the chip so 32 all to gether

Ok... Those appear to be 256k*4bit ZIP chips.  32 of them would give the card a total of 4MB working RAM.  

The AMD AM95c60 is the graphics processor of your card.  I can't find any supported Amiga cards with that chip.  Most likely the custom simulator software is the only thing that runs on this board.  Bummer.

damn the takes the piss  :madashell: oh well no bigy i guess ( can't sell them ether)

[aardvark]

( can't sell them ether)

If they're the kind of zip chips they used in thae A3000 or Bridgeboards, you may have a market for those alone as they usually go for a good price.
Don't know what kind of accelerator you've got in that one (a 68020?) butif you have one, try to get 3.1 roms for A2000/500s install them, and then get a copy of AmigaOS 3.9.  Also recomended is a megachip Agnus adapter or equivalent to bring up your chip ram to 2 megs. I ran an A2000 for years (still have it, but I love my A3000T) on ! meg of memory, but when I finally broke down and put a hard drive in, the mere fact that it was there soaked up enough memory so that many programs no longer ran. I installed a different hard drive card that also had another 8 megs of memory and I thought I'd died and gone to heaven.   :-D

this is my accelerator card http://www.amiga-hardware.com/

where should i try and get  3.1 roms from i'm looking on ebay but no look realy

you'll need to check the ROMS on that actual accelerator card before you get the new OS because chances are that your boards rom revision won't be compatible with version 3.1 of workbench.

It's because if you hold both mouse buttons down at startup, you get the a2620 accelerator boards config screen and the newer operating systems use the 2 mouse buttons at startup to display the early boot configuration (which workbench 1.3 doesn't have). Have a look on the actual ROM chips on the accelerator card; there's 2 and they're at the top near the left hand side. it should say a rom version on them.

So if you get the new operating system you'll probably have to take out the accelerator before you can use it. that's what I had to do.

i can't see any rom numbers which chips should i like on in my last post i had a link that the card can you should me on it

edit nop its not there its here http://www.amiga-hardware.com/a2620.html lol

[lordnicon]

errrr mate i did the " 2 mouse buttons at startup to display the early boot configuration" thing and it says
AmigaDos on 68000
AmigaDos on 68020
Amix

[Ilwrath]

AMIX??!  Does this option work?  Maybe your simulator software is actually on the AMIX (Amiga UNIX) boot?

What unique machines you lucky folks have.

[lordnicon]

well thats a no it does't work

[lordnicon]

so what should i update/upgread to get my A2000 working well

where can i buy stuff in the uk from

[lordnicon]

ok i think the ROMs are on the right and one says
390282-04
A2620 U4
ODD 9EB2

and the other says
390283-04
A2620 U5
Even 4B70

what ever that means lol

These are not RCA but HF-PCB connectors. The same kind was used on the Visiona graphics card. It's like a predecessor of BNC connectors, offers better signal quality than DB9.

hey again. I tried posting on this topic a few days ago but it wouldn't let me. I wrote quite a lot too! it was annoying! anyway, i'm not too sure if the numbers on your ROMS tell us the revision. I think the -04 at the end could be the revision though because I remember finding out I had one board with Revision 3 and one had 4 so it would figure that yours are of a similar revision i guess (same company etc).

[lordnicon]

is there a better way to find out what my roms are

and i'm sorry your post did't work.


i want to change the ROMs on my mobo do i need to change the ROMS on my hard drive card too?
