Did I get >all the permutations? If Mark is right about 512K and 2MB SIMMS, then >you could have -- oh forget it! The Mac IIsi has one bank of 4 SIMM slots, not 2 banks of 2. Thus, you have to fill all four slots with the same kind of memory. With the one meg of on-board RAM you get: 256k SIMMs: 2 Meg RAM 1meg SIMMs: 5 Meg RAM 4meg SIMMs: 17 Meg RAM At a meeting with some Apple folk, we were told that 512k SIMMs and 2 meg SIMMs are going to be made - and that Technology Works was already manufacturing the 2 meg SIMMs. However, this was mentioned in the context of discussing the Mac LC, and not the IIsi - I am uncertain whether or not these two new SIMM types are LC-only (like the IIfx's screwy SIMMs). Please note crosspost to c.s.m.hardware, and followup accordingly. -- +-----------------------------------------------------------------------------+ | Jim Gaynor - The Ohio State Univ. - IRCC - Facilities Mgmt. - OCES | | Email [gaynor@hpuxa.ircc.ohio-state.edu], [gaynor@agvax2.ag.ohio-state.edu] | |_ "Don't tell me truth hurts, little girl; because it hurts like hell..." _|
