Hi MontrealCL,
The very first thing that you should do, if you have not done it already, is to REMOVE THE BATTERY FROM THE MOTHERBOARD!!!!
For a nice starter Amiga 2000 setup you will need the following:
Commodore A2091 board with 2 megs of ram
Commodore A2630 (68030 board) Rev 9 with 4 megs
Commodore A2320 (Amber board)
ViewSonic or other nice VGA Monitor
2 - Disk Drives
1 - SCSI Hard Disk (between 500 megs to 2 gigs)
1 - SCSI CD-ROM Drive (12 speed or LESS)
Kickstart 2.04 or 3.1 ROMs
After you LEARN how to use your Amiga 2000 then you can upgrade it beyond this level. :-)
