What is it?

Its a chip RAM memory expansion for Commodore Amiga 500 computer, it provides 512 KB of additional chip RAM.

Includes switch to disable the expansion.

As well, it is compatible with Amiga 500 Plus; but for these ones I also manufacture a 1 MB chip RAM expansion board as an option of this product.

Fully assembled and tested via RAM tester software.

Why did you make it?

Some time ago, I updated an Atari ST machine with a custom RAM upgrade... many RAM modules where left at their own at the desktop´s drawer.

As well, at my surroundings, there was a lack of Amiga 500 Plus trapdoor expansion modules; these manufactured devices come to fullfill this need.

What makes it special?

Despite 512 KB its the basic expansion module for common Amiga 500 computer, this trapdoor was originally designed for Amiga 500 Plus
