A2000 What Card Is This?

[Ofoosy]

I got my first Amiga quite a while back from this old man on  craigslist  and I haven't really done anything with it because of some  problems I  have with this card that have no idea what it is it has a  port where a  hard drive goes (and it came with one) If the card is  plugged into the  Amiga it wont boot if its removed it works just fine  and its just that  card and nothing else
 
Does anyone know what this card is and what it does

GVP 68030 Accelerator. G-Force 030 early version. Here is a reference:

The card actually does three things.
 
1. It is a hard drive controller, easy to see since it has the hard drive attached to it. Make sure the drive cable is connected pin 1 on the card to pin 1 on the drive. Sometimes the cable can be twisted the wrong way. Easy way to test, unplug the drive from the card and see if the Amiga boots
2. It is a RAM expansion. There are two SIMM modules and some RAM just above those two soldered to the board. (that is the last picture you posted). I cant tell well from the picture but it looks possible the top SIMM (in between the lower SIMM and soldered RAM) might not be fully installed. If either side is not clipped in, this can use an issue. You can also try taking out the two SIMMs and install the board and try to boot the Amiga. This will check for a RAM issue with one of the two SIMMs
3. It is an 030 accelerator. This card on boot up replaces the 68000 on the motherboard running at 7mhz, 16bit with a full 32bit system including 32bit RAM to accelerate the Amiga. If something is wrong with this, it can be a big problem. But you can check the jumpers at J5, J6, J11, CN8 to make sure they match the speed of the 68030 CPU on the board. Compare them to the info on the page Ami GFX linked to above.

Yes, looking at the picture, there are only 2 simms. The middle simm slot looks empty. That might be the problem. Try booting it with no simms and then put them back in one at a time if it boots and put the second simm in the middle slot, not the last one. The jumper settings are in the reference in The Big Book of Amiga Hardware: http://www.amiga-hardware.com/.
