A500 512kb memory ram trapdoor expansion new from amiga kit
A500™ 512Kb RAM trapdoor memory expansion. - new revision available
![]() This high quality, low cost memory expansion doubles your Commodore Amiga 500 computer's memory. Extra memory is essential for many games which require 1MB of RAM to work. System RAM will be increased from the standard 0.5MB (512kb) to 1MB (1 megabyte). Installation is straight forward process: simply slot the A500™ memory expansion into the trapdoor slot. The trapdoor bay is covered by a small plastic door underneath the Commodore Amiga 500 computer which can be easily levered open. There is no need to unscrew, open or disassemble your computer. Memory expansion features Real Time Clock header to install optional Real Time Clock module: available installed at special price below or available separately here. Features: 0.5MB RAM to boost total system memory to 1MB Memory auto configures with no drivers required Header for optional Real Time Clock module: available installed at special price LK1 jumper on board: used for enabling 1MB Chip RAM modifications (Agnus 8372 or higher required). Two-page colour manual included Commodore Amiga 500 Plus users: we have produced a separate 1MB memory expansion available here Important note about inferior third-party expansions: our A500™ Memory Expansion features resistor arrays on board to limit the rising/falling edge of some high speed signals. Without these noise can be introduced and result in memory working unreliably. Unlike our tried-and-tested design, some third-party budget boards cut costs and do not feature the resistor arrays which can lead to memory reliability issues. Revision 2, updated from our original 2007 product design. Fully tested on revision 5 and 6A motherboards. This product is manufactured by Amiga Kit offering high quality upgrades for your Amiga computer at good value, low prices. Copyright 2007-2019 AmigaKit Ltd.

At this price. Getting an older card makes no sense!
Does AmigaKit do additional discount for forum users? ![]() |

Hi
Thanks for the warm words. We have made the price as low as possible. Note the further discount on a Real Time Clock when bought with this card. We are producing hardware at affordable prices to ensure we can enjoy our hobbies. We have noticed recently a big increase in part time resellers overcharging on Ebay and their stores for hardware. |

The board on 1MB seems to suggest it can be used on A500 at 512K yet description states only for A500 Plus?

Thanks Mark! We keep working on new Amiga projects because of your longstanding custom and other regular customers.
@lesta_smsc There are two versions: A500 0.5MB version (1x RAM chip on the board): https://amigakit.amiga.store/product...roducts_id=767 A500 Plus 1MB version (2x RAM chip on the board): https://amigakit.amiga.store/product...roducts_id=502 You probably notice that both versions share the same PCB. |

Mark,
Unfortunately only Rev 8 boards (A500 Plus) can have 2MB Chip. |
