The 256Kbyte SIMMs I got in my IIsi a couple of months ago where actually 2 256Kx4 1Mbit DRAM chips. I would guess that the 512Kbyte SIMMs are actually a 4 chip version of the 256K ones they use to ship. -- ---------------------------------------------------------------------------- Brian McClendon bam@rudedog.SGI.COM ...!uunet!sgi!rudedog!bam 415-335-1110 ----------------------------------------------------------------------------
