16 banks of internal 2Kb auto-backuped SRAM.

And now, the equivalent of 16 x 6116 auto-saved memories for your favorite vintage machine like :

• Alpha Juno 1-2
• Juno 106
• JX-3P
• MKS-30
• JX-8P
• JP-6
• TR707
• Prophet 600
• DW6000
• DW8000

and many others...

On the past, I developed a simple solution that had the disadvantage of only using part of the new memory component:

Very effective solution, for example inside a Roland JX-8P :

But, only 2Kb are used on the 32Kb that contains the new RAM.

So I decided to do a new version with an additionnal connector for the extra addresses selection :

The J1 connector will allow to select the memory bank using an external selection solution.

The other side of the board :

This board will be a little bigger than the previous version but still very closed to the original size of a 6116 SRAM chip :

Once this card will have been tested, it will remain to develop the board of the memory banks selection system.
