To all the mighty Amiganous Gods
 I humbly address this queation
A2091 stock standard scsi 2 meg on board
how do I use the  A2000-scsi+8 ram
what jumpers do I reset is it dangerous to try without knowing
What slot do do I seat it in
ie the cpu or one of the others
as there are three posibilities

A2091 settingsJumpers (from TBBoAH):

JP1: Memory Size
0K: Set for no memory.
512K: Set for 512K of RAM.
1M: Set for 1M of RAM.
2M: Set for 2M of RAM.

JP2: Autoboot Enable
AUTO: Set to enable autobooting from the A2091.
DIS: Set to disable autobooting from the A2091.

JP3: Interrupt Select
INT6: Select interrupt 6.
INT2: Select interrupt 2.

 Notice that the A2091 is a slow and unreliable SCSI controller (it not work OK with CD and other removable media). The GVP HC+8 is a SCSI-2 controller (faster) and can hold up to 8Mb directly on it. Just sack out the 2091 and just keep the GVP SCSI controller.

 Pretty much anyone! The Amiga have auto-configuring. Drop the card inside it and be happy. :-)

You're giving the answer to that question yourself... Read the first line again.

thank you  Jiffy et al

I have a hard drive expansion card you can mount your drive with. Will include a SCSI cable. Alas, it also takes up a card slot in your 2000.

The card you have used a bracket mount to stand-off a hard drive flat on the card. There are 2 mounting holes at the rear. The bolts and nuts that attached the bracket were nylon. It had nylon pegs as stand-off's near the center of the card.

I have two 6.0 roms from an A590 are they compatible with the A2000-scsi+8 ?
