This board was sold and marketed as Sakura 4MB PCMCIA SRAM, primarily by Sakura IT, though several forks of this design exist.
Add 4MB of Fast RAM to your unexpanded Amiga 600/1200. This additional memory will make your system much faster and allow to run more demanding games and applications. It was designed by Jarosław Bieliński and Radosław Kujawa.
This memory expansion card has the following features:
We did our best to ensure that this card works on as many configurations as possible, but some accelerator and Fast RAM expansion designs are inherently incompatible with PCMCIA slot if more than 4MB of memory is installed. Note that PCMCIA SRAM should work with them anyway, if less than 4MB Fast was installed on the turbo card. Of course, if you don’t have any accelerator, you don’t have to worry about that.
The following A1200 cards are known to be PCMCIA compatible and should work correctly with any amount of memory installed:
The following A1200 cards are known to be problematic if more than 4MB of memory is installed:
The following A600 cards are known to be PCMCIA compatible and should work correctly:
The following A600 cards are known to be problematic if more than 4MB of memory is installed:
