The SIMM stackers for the IIfx are for 64 pin SIMMs. What makes the IIfx's SIMMs special is that they have separate pins for data input and output. This allows to overlap read and write accesses to the memory, but it also makes 30pin -> 64pin adaptors impossible. -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
