This particular Amiga 500 has been upgraded with a Kickstart 2.04 ROM, and a GVP A500-HD+ SCSI controller housing a 50meg Quantum hard disk and 4meg of FastRAM, for a total of 5meg of RAM. Besides the GVP SCSI controllers for this machine, which had space enough to hold a single 3-1/2" hard disk internal, there were also a number of excelerators available for it, including the Supra Turbo-28, which used a souped up 68000 CPU, to the A530 from GVP which used a 68030. There were also a number of different motherboard revisions, with Rev 3 being an early example, the Rev. 5 being the most common and which usually shipped with the 512k Agnus chip, to the Rev 6 and above, which are less common and which may be found with the 1meg Agnus chip, which would allow you to use the internal 1meg of RAM as all chip RAM. Some Rev 5 and below mainboards are known to have compatibility problems when trying to use any of the OS ROMS above 2.04. Silk screened on the A500's mainboard is the codename 'Rock Lobster'.
On April 29, 1994 Commodore International shut it's doors, and on June 20th 1994 Jay Miner passed away.
