Release Price $1500+

 

      Above is the A2000HD. It is the same as the A2000 except it was released with a hard drive on a A2091 Hard Card. The Hard Card has been removed and replaced with a 540 MB SCSI hard drive installed in the left 3 1/2 inch bay that is shared by both the A2000 and the 286 Bridgeboard PC. It has 9 MB of RAM and an A2230 'Flicker Fixer' video expansion card to adapt the Amiga to use a standard VGA monitor. It has an A2286 Bridgeboard (Intel 80286 AT computer on a card) installed and an IBM 1.2 MB floppy drive.

      I have this computer setup on my workbench as a working computer along with a 486DX2 PC which is adapted to use a Commodore 1571 floppy drive to download C64 games stored on CDs through an XE1541 cable. I call my workshop the Commodore wing of my museum because I have all the various Commodore computers in my museum set up there and stored on the shelves in that room. To read more info about the A2000HD see the A2000 exhibit.
