The Radius Rocket does cause some software incompatibilies, but they can be overcome by turning on/off certain caches etc. This may sound like a pain, but you can configure the Rocket to recognize incompatible applications and set itself accordingly. Also the Rocket will not work with any Graphics Accelerators. --Scott -[ Scott E.

Apple has said before that these things are bad and should not be done... Applications with '040 incompatibilities will definitely want to fix them- selves if Apple should happen to announce an '040 Macintosh. >This may sound like a >pain, but you can configure the Rocket to recognize incompatible >applications and set itself accordingly. Yes - the '040 cache modes can be disabled on a per-application basis, through the RadiusWare control panel. >Also the Rocket will not work with any Graphics Accelerators. The SuperMac and RasterOps Graphics Accelerators are not compatible. The SuperMac Spectrum/8 PDQ and Spectrum/24 PDQ do work, although the graphics accelerator INITs are not compatible with Rocket. For more information about Rocket and display interface boards, see my related posting which was a followup to someone who asked about RasterOps compatibility. In addition, the Rocket is in itself, a graphics accelerator. It uses the NuBus block transfer to accelerate video boards much in the same way that the Radius QuickColor or Apple 8*24 GC cards do. Therefore, a separate accelerator is not really necessary. -- ----- Steve Lemke, KC6QDT - Software Engineering, Radius Inc., San Jose ----- ----- Reply to: lemke@radius.com -- U.C.

Were I to put one of these into my Mac II (with the original ROMs),
would I:
1. Have to get the motherboard upgrade to the newer ROMs
2. Be able to bypass the 24-bit addressing limitations/bugs in the
Mac II ROMs (or would a 32-bit clean ROM still be necessary
in order to reference an address space > 14MB)?

From the Rocket Read Me file, regarding Mac II's with revision A ROMS: "Rocket is incompatible with early Macintosh II's that are equipped with Revision A ROMs. The Revision A ROMs are only found in Macintosh II computers manufactured before January 1988. Please contact your authorized Apple dealer for upgrade information." > 2.

If they're 32-bit clean, then you do 32-bit clean stuff. > (or would a 32-bit clean ROM still be necessary > in order to reference an address space > 14MB)? Yes and No. Programs like Maxima, Virtual, and/or Optima should shortly be Rocket-compatible. Contact Connectix for more information. -- ----- Steve Lemke, KC6QDT - Software Engineering, Radius Inc., San Jose ----- ----- Reply to: lemke@radius.com -- U.C.
