The ElkSD64 has proved to be extremely popular, but people regularly
asked if there was a version that would work with the Plus 1 expansion. Those requests lead directly to the ElkSD Plus 1.
The ElkSD-Plus 1 is a combined SD card interface and RAM expansion in cartridge form, which works in a Plus 1 cartridge slot. But it's not just an ElkSD64 squished into a cartridge case, it actually boasts considerably higher performance due to a re-designed SPI controller; performance is on par with the ElkSD128 and MasterSD. The cartridge case is a custom 3D printer case.
The Plus 1 cartridge slots are limited to two 16K memory banks per cart, as one bank is used by the MMFS ROM this means the 32K of RAM on the ElkSD64 has had to be reduced to 16K on the ElkSD Plus 1, resulting in a total of 48K usable RAM on the Electron.
The ElkSD Plus 1 is available to buy via EBay.co.uk. Click the Ebay logo to view the product page.
