Co. - Advanced Technology Lab - St. Louis Lines: 30 As if this has been hashed to death in the past, please email to me rather than taking up net bandwidth. I'm thinking about going the 'blessed' route to 68030-ness (the Apple upgrade from Mac II to Mac IIx). The list on this is $2,199 for just the motherboard. As I understand it, this is just the board swap where they take (rip? :-) out your machines motherboard and put in a IIx motherboard and then move the SIMMs on your original motherboard to the new one. By the way, I am aware that the drive upgrade is $599 (and requires the IIx motherboard). What's the scoop on third-party boards? How compatible are they for things like A/UX, SIMM usage, SIMM speeds required, etc? On a bit of a tangent: does anyone out there have an idea of what sorts of speeds you'll need in your SIMMs to take complete advantage of a 25Mhz machine? I've got this sinking feeling that you'll need 80ns or better and all these 100ns SIMMS will induce wait-states or some other undesirable effect(s)...
