I was planning to buy the CMI board with the math processor to help speed up some ray tracing I am doing... Im using QRT, which suprisingly enough does a decent picture in about 30 minutes. Can anyone guesstimate what the speedup will be? Also, can someone _please_ inform me as to where I can get a cable to allow me to display my IBM ega graphics output on my amiga monitor. I could probably make it myself, but I really dont want to bother if it is availible already. (no flames about my *BM !!)

You can notice a decrease in the amount of time that it takes to calculate with the processor at 14MHz. I believe that I was getting in the area of 80% or so increase in speed when I was doing the preliminary tests on the Accelerator.

The sync rates are VASTLY different. And if you HAVE a multi-sync monitor, you have to tell us which one before we can help. -- Michael J.

I have a couple of questions about CMI's 68000 2x board.
I have the Spirit inboard installed in an A1000. Can the 68000 2x board be
jury rigged to work with the Spirit board? Such as:
Spirit Board ---> 68000 2x Board ---> Motherboard
I realize this would require modification to the Spirit board.
If so, would I have to change PAL chips also?
Any suggestions?? Thanks!
