From the project
Use a modern Apple IIe RAM card with a RamWorks-style RGB piggyback
This card provides a way to use a modern Apple IIe RAM card (such as the GW4203B from Garret's Workshop) with a RamWorks-style RGB piggyback card.
For the RGB piggyback, it is compatible with classic piggyback cards like the Applied Engineering RGB Card, Digital Prism, and Color Link, as well as the a2heaven VGA piggyback card.
For the RAM, the GW4203B is recommended, but you could also use one of the older GW 2MB cards, or one of the "small" Apple 80-column cards. (But why?) It just needs to be 2" tall or less.
