This reporsitory contains severals design of RAM expansion boards for the Sinclair QL, some of them area new design, and other are reverse enginiered of products seld in the 80's for the sinclair QL:
New design in 2026, based on qubide card of liont, https://hackaday.io/project/183490-qubide-clone-with-640k-or-704k-ram-upgrade-for-ql
Include a 1Mbyte StaticRam in a very small board with pass-through. This is the prefered design if you are new to the Sinclair QL
My old 2022 design, based on qubide card of Jose Leandro and work of McLeod Ideafix, using a 512Kb StaticRam in a very small board with pass-through. two of this board can be stacked to achive the 892Kb of RAM that is the maximun possible on a Sinclair QL
