ElkSD128 - SD Card Interface, 128K RAM Expansion & Joystick Port for the Acorn Electron


The ElkSD128 is an all-in-one expansion that enables the Acorn Electron to load and run disk images from a standard SD memory card. It also incorporates a 9-pin digital joystick interface that offers wider game compatibility than any previous Electron joystick interface.

In addition, the ElkSD128 includes 128K of sideways RAM to bring the Electron up to a total of 160K. Sideways RAM can be used for loading ROM images or for playing games that require more then the standard 32K.

If you want to easily and quickly play all those classic games on your Electron, the ElkSD128 is for you. Designed as a more capable version of the best-selling ElkSD64, it is the most complete expansion unit for the Electron with a wide range of features that include:


An SD card is not included with the ElkSD128.

If your Electron has a Plus 1 interface attached, please take a look at the ElkSDPlus-1. The ElkSD128 is not compatible with the Acorn Plus 3 disk interface unit.

(*) Many SD cards up to 64GB have been tested and found to work provided they are formatted as FAT32 and partitioned to less than 8GB, but this is not guaranteed. Use of 1-8GB capacity cards of a reputable brand, such as SanDisk, Samsung or Kingston, is recommended.
