I only have experience with Attractors. Our setup is:

Quadra 800 (68040 33 MHz, 8 MB RAM) System 7.1, 7.1.2
PowerMac 800 (601 66 MHz, 8 MB RAM) System 7.1.2

(A PowerMac 800 is a Quadra 800 with a PowerMac Upgrade Card installed in
the Processor Direct Slot [PDS]). So, actually, the Quadra 800 and the
PowerMac 800 are the same machine; the CPU is determined at startup, either
the 040 or the 601.

I just tried the both FPU- and nonFPU-Attractors on the Q800. The nonFPU
version was computationally slower, but still quite usable. I imagine the
LC630 would be comparable in speed.

Apple makes a Macintosh Processor Upgrade Card for Macintosh Quadra 63x
computers. This should turn your LC630 into a PowerMac 630, 601 66 MHz,
or roughly the equivalent of a PowerMac 7100/66. This way, you should have
"the best of both worlds"; that is, an LC630 to run 040 programs, and a
PM630 to run 601 programs. Since I do not have direct experience with an
LC630, I would suggest that you verify Attractors will run on the LC630 at
a speed acceptible to you; also, you should verify that the Macintosh
Processor Upgrade Card functions in a manner acceptible to you.

Good luck!
