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.

What does this bit mean?? Does it mean you dont have to do the mod on the motherboard, you just enable this jumper and you get 1MB ChipRAM?

Hi

Yes that is correct assuming you have a full ECS chipset - commonly found on Rev 6 and above.
