The newest official OS is 3.9. There is a new copy on EBay right now with the bidding at $25. It only comes on CD so the first thing I would get for your A2000 if I were you would be either an external or internal SCSI CD-ROM drive. Are you going to use the SCSI on your Combo card or the seperate SCSI controller you mentioned? The 100mb harddrive is also very small so I would get maybe a 4gb one. They are relatively inexpensive these days.
