I have an Apple IIc with a bad memory chip. The chip is labeled 4264 without any dash number (speed) and branded as Apple. This is apparently a Micron 64k x 1 DRAM chip with industry standard DRAM pinouts. Does anyone know if I can use a 4864-3 that also appears to be an Apple branded Micron part? This most likely was pulled from a working 128K Macintosh many years ago. I could not find a Micron PDF for a 4864, but a Hitachi 4864 seems to have the same pinout as the Micron 4264. thanks in advance, Mike Willegal
