Based on the renowned GEM WS2 Keyboard technology, the GEM WS400 enhanced the already excellent WS2 features, with a 88 note dynamic weighted keyboard.
Issues: The WS Series has SRAM for internal storage. This SRAM (Static RAM), uses a rechargeable NiCd backup battery which is prone to leaking and the battery acid when leaking, often corrodes the PCB and components. Recommend changing the NiCd battery immediately for a separate battery pack, mounted away from the PCBs.
Upgrades: The Operating System (Firmware), is stored in EPROM (erasable programmable read-only memory). Various releases were made and can updated to the latest (at the time). The EPROM releases can be found in GEM & LEM EPROM Information and all EPROM BIN files can be found in the GEMClub Members Downloads area.
Disks: A large range of GEM and GEMClub members disks can be found in the GEMClub Members Downloads area.
