The extra RAM is classified as &quot;fast&quot; RAM, but is sometimes referred to as &quot;slow&quot; RAM since due to the design of the expansion bus it is actually on the chipset bus. Such upgrades usually include a battery-backed real-time clock. All versions of the A500 can have the additional RAM configured as Chip RAM by a simple hardware modification, which involves fitting a later model (8372A) Agnus chip. Likewise, all versions of the A500 can be upgraded to 2 MB Chip RAM by fitting the 8372B Agnus chip and adding additional memory.&quot;"}
