4 Description About The IIGS8MRAM Card Memory Expansion IIGS8MRAM cards allows you to increase the Random Access Memory (RAM) capacity of your Apple IIGS. RAM is the memory that can be both read from and written to-the addressable (user useable) memory. Many programs automatically look for and use available RAM to give them more room to operate (desktop space). Many programs load themselves into the available RAM at start up. This greatly increases their performance because it reduces or eliminates the need to access the relatively slow mechanical floppy drives. IIGS8MRAM lets you increase the available system RAM 8MB. IIGS512KROM add-on board allow you to add ROM chip (as they become available) which will give you greater speed in loading tools, applications, etc. DMA Support The Apple IIGS is limited to expanded system memory of up to 8 Megabytes but only 4 Meg is Direct Memory Access (DMA) compatible. Most DMA peripherals will tell you that they require DMA. IIGSRAM8M cards are DMA compatible.

Insert the new battery, positive (+) side up. Lithium Battery is using to keep SRAM data after PCB lose power.to using battery backup SRAM you needed to use custom software driver to use RAM as solid state RAM disk because build in Smart Port RAM disk driver on GS Firmware clear RAM content after power on an you cannot use it. Driver is in development stage and will be ready soon. Apple IIGS 8M RAM User s Guide a2heaven.com, 22 Nov 2016 Version 1.00 P a g e 11
