Pic One:
A rev 4 A2000 mainboard
(most common 2000 model is actually the B2000 which was designed in west chester. Note that this rev 4 comes from germany, has NO buster chip and has only half of a video slot. Also does this version not have a composite video out next to the audio jacks) Full size picture is here:

Pic Two:
The original "A" 2000 (rev 4) 1MB memory expansion fitted to the MMU slot (later badged CPU slot)
Here is more info:

Pic Three:
The other board is a A2088XT Bridgeboard, more info here:

Basically what you have there is a pretty incompatible A2000, don't expect to many CPU cards and/or zorro cards to work on this machine. It is however a very nice early example of what the A2000 would later become and certainly has a great collector's value I suppose.

What I see in pic #1 is the MoBo. I have Rev 4.4 and
a Rev 6.2 (I think), its not quit the same as either of
my boards so I'm not sure what rev it is.

In pic #3 I see a turbo card in the cpu slot, not sure
what brand .. (Not commodore).
A SCSI card maybe Supra, and a ram card.

The card in the CPU slot looks like a CBM A2000 1Mb fast ram card (http://amiga.resource.cx/photos/photo.pl?id=a2001)
The full length Zorro card looks like a CBM A2088XT bridgeboard (http://amiga.resource.cx/photos/photo.pl?id=a2088xt)

But as for the ISA card in the bottom, no idea from that shot.

Edit.. beaten to it by Tahoe :lol:

To be honest, i dont think anyone can help you with photos that are that bad quality. Can you not get anything less blurry?

Hi,

> it seems to be any SCSI interface

I agree, it looks like a SCSI-Interface.

> but for ISA slot??

Why not? The XT ISA-slot is an 8-bit bus with upto 8 MHz, a SCSI-I bus is also an 8-bit bus with 5 MHz, so the ISA-bus will not be a bottleneck and the SCSI-standard is very old.
