Hello. I previously have had a CMI Processor Accelerator (which is now owned by DigiFX I believe). It has a speedup factor of about 10% for most things, except, or course, its demos that use it's own fpu.library, that demo multiple times the increase. Now after seeing the April AmigaWorld, and it's rating of the different boards it basically said: "The ICD AdSpeed accelerator gives speed increases of 65-100%, and performs better than any 68020 board w/o additional ram due to the fact that it employs 2, 16K Caches for both instructions and data, to speed up writing to fast ram." Since I think it it is now available at around $209 from a few mail order houses, I was tempted to get it. However, I would like to hear what others have expierenced with it. (I.e. will it _REALLY_ work with everytthing, including the Bridgeboard or other DMA devices) The CMI/DigiFX PA will not without hardware modifications. The PA board also would cause the serial port to lose incomming data once the computer warmed up above 80 degrees or so (room temperature). Every other character would be lost at 2400 baud. sometimes much worse. Thanks for your help. mail to blf@churchy.ai.mit.edu or post here.
