RAM2E II (GW4203B) provides the Apple IIe with 8 MB of auxiliary memory and enables double-high-resolution graphics and 80-column text display modes.
Low-Power, SDRAM-Based Design
Thanks to a modern, low-power design, RAM2E II uses only 0.2 watts (40 mA @ 5V) in typical use and 0.4 watts (80 mA @ 5V) in heavy use with an accelerator[1]. Unlike other IIe auxiliary memory cards, which are built with vintage asynchronous DRAM chips, RAM2E II uses modern SDRAM. This design allows for low power consumption and improved reliability over other memory cards using 15+ year old chips.
Small Size, Low-Profile
RAM2E II features a small board outline and is the thinnest Apple IIe auxiliary memory card ever produced, at under 4mm thin. Small and thin dimensions improve the mechanical compatibility between RAM2E II and peripheral cards installed into the IIe's Slot 1.
Adjustable Capacity, Highly Compatible
RAM2E II is highly compatible with existing software. An adjustable capacity feature allows the memory size to be set to 64 kB, 512 kB, 1 MB, 4 MB, or 8 MB, improving compatibility with software expecting a particular memory capacity. Capacity settings can be set temporarily or saved in nonvolatile memory. The capacity adjustment utility is available on our website.
Ecologically Friendly, Gold-Plated PCB
RAM2E II features a lead-free, ENIG gold-plated, 4-layer PCB and is fully EU RoHS-compliant. All units are tested extensively before shipment. Only new parts are used to build RAM2E II, and all RAM2E II cards are manufactured in our semi-automated facility in Columbus, Ohio, in the United States.
Open-Source Design
RAM2E II's design is fully open-source. The schematics, board layouts, CPLD firmware, and utility software are all freely available for commercial and noncommercial use. To download the design files, visit the Garrett's Workshop GitHub page.
Note for Revision A Apple IIe Owners
If you own the uncommon revision A Apple IIe and are interested in RAM2E II, please read this! RAM2E II requires a small modification to be compatible with the with the rev. A Apple IIe. The modification consists of removal of the “DHGR” jumper resistor. If you have a rev. A Apple IIe, please contact us before purchasing and we can make the modification before shipping your RAM2E unit. However, do note that with the modification made, RAM2E II will not support the double-high-resolution graphics display mode.
