   Hello MCL users -

   Erann Gat asked:

   >I have heard various stories about incompatibilities between MCL and

   >any other known incompatibilities?  

   and, from Bob Hall:

   >I am interested in "reclaiming" a IIci to run MCL on (it is
   >currently 3-6 times slower than my IIfx, depending on which

   >Does anyone have any experience (positive or negative) with the various

   People ask this question fairly regularly (here or in email to us at
   Apple), and I'd like to put together some sort of answer. If you have any
   experience running MCL 2.0 on any accelerator boards, please send me
   (mark@cambridge.apple.com) answers to the following:

	   What type of accelerator board (please be specific, and include 
		   version numbers, amount of RAM, etc.)?

A Radius Rocket 25Mhz with 16Meg running the Radius Share software

	   What type of Mac is the accelerator board installed in (include 
		   amount of RAM, System version)? 

MacQuadra 950 or MacFX

	   Do you use any "non-standard" extensions/INITs?

	   Do you run with VM enabled?

	   Did you have any problems getting MCL to run?
Yes. MCL seems to be the only appliation which will not run.  Upon launching
MCL on the Rocket Board I get an immediate error Unimplemented Trap then upon
continuing I get an error message error type 12 occured.  I'm very unhappy!!

	   Is PTable installed?
   If you can, please also include the results of evaluating these forms in
   MCL running on the accelerator:

	   (ccl::gestalt "fpu ")           ; note the space after the "u"
	   (ccl::gestalt "mmu ")        ; note the space after the "u"
	   (ccl::gestalt "romv")

   Please include any other comments you have as well.

   I'll compile your responses and post a summary here. 

   Many thanks for your help.
