Could someone at Apple tell us:
1. If you use the new 8-24 GC card in 1-bit mode, do you still get
the benefit of QuickDraw acceleration, and if so, about how much?
2. Tell us about the SIMMs on the IIfx. Are they compatible with
anything already on the open market, or are they different?
3. Who makes the 160 MB drives you ship?
Thanks

The SIMMs in the IIfx are the same style as LaserWriter SIMMs, that is, it's a 64-pin connector instead of a 30-pin connector. The difference is the speed. The IIfx requires 80ns, all the LaserWriter SIMMs I've seen are 120ns. I don't know if they're available from 3rd parties, but I'm sure they soon will be... --clark -- ----------------------------------------------------------- Clark Anderson InterNet: anderson@apple.com CPU Engineering AppleLink: C.ANDERSON Apple Computer, Inc BellNet: 408-974-4593 "I speak only for myself, much to my employer's relief..." -------------------------------------------------------------

The difference is the speed. The IIfx requires 80ns, >all the LaserWriter SIMMs I've seen are 120ns. I was under the impression that the extra 32 pins on a LaserWriter SIMM were individual bit-enable lines, and that the extra 32 pins on the 'fx' SIMM are output data lines. Is this not true? How many wait states do the 80ns SIMMs cause, and is there any provision for using faster memory someday? (and of course, we all want to know if its possible [for a 3rd party] to engineer an '040 drop-in replacement for the '030) Marc Kaufman (kaufman@Neon.stanford.edu)

The 1*8 card can be upgraded to an 8*24 since they are the same card with varying memory. The 8*24 and the 8*24 GC are substantially different cards. David W.

No. According to the latest MacWeek I read (3/20) you can upgrade by adding memory from the 4*8 to the 8*24, but there is no upgrading to a GC. Sorry.
