Dear Moderators: I think the following report on the DayStar PowerCache performance in LC's would be a useful addition to the info-mac/reports directory. The following explanation of how the PowerCache minimizes the effect of the LC's 16-bit data path was written by Steve Tuttle, the Online Resources Mgr for DayStar Digital. I will submit an expanded report to the info-mac archives as soon as Steve forwards the results of the benchmark tests on the unenhanced LC and IIci, but the results as presented give a good indication of the performance difference between a PowerCache-enhanced LC and IIci. "Altho it would appear intuitive that due to the 16 bit path on the LC you are going to be forced to run slower, it is not necessarily the case. You see, all Macs have some sort of delays inherent in their design: The II,IIx,IIcx, & SE/30 all have 120ns RAM and require 2 wait states to be added to the memory
