I just looked at the Big Book of Amiga Hardware web site.
http://www.amiga-hardware.com/To my surprise, the company I was most familiar with for Amiga 2000/3000/4000 accelerators is not listed in there.
RCS management, located right where I live in Montreal made the Fusion forty accelerator
http://amiga.resource.cx/exp/fusion40It is said that: The Fusion Forty was used in the amigas which have done parallel rendering of images for the TV series 'Babylon 5' at Foundation Imaging.
http://www.vintagecomputercafe.com/amigafusionfortyaccelerator.htmIt is also said that it was the very first 68040 accelerator ever for the A2000.
RCS also did the X-Calibur, the only "accelerator for an accelerator" that stacks on top of the A3640.
