Recently I picked up a Yamaha FL512M Flash Expansion board from an eBay sale.
I bought this card primarily to upgrade it to 1GB using the 4x JS28F00A Flash ICs leftover from the Mutec FMC-05 Upgrade Project.
Unlike the Mutec board this product is a double-sided design:
FL512M Version: 512MB capacity with one side populated.
FL1024M Version: 1024MB (1GB) capacity with both sides populated.
Upgrading the card to 1024MB should be as simple as fitting the missing components to the unpopulated side.

Bill Of Materials:
Using a photo of an original FL1024M board as a reference a Bill Of Materials was compiled:
Once the missing components were fitted the board was looking complete.
After the board was cleaned the serial number was moved to show FL1024M rather than FL512M
The MOXF took a while to format the board and finally declared 1022.5MB under the hood 🙂
