I got some slightly strange results, which seem to be dependent upon the machine that x48's running on, so I'm interested in knowing if anyone's done the test on a real 48SX, as I haven't seen one in pier4r's list of results. My program's below, but it's pretty much the sum from 1 to n for the original formula.

Oh, and I finally managed to find a PDF manual for the SX; as most of you know, there are quite a few differences between the SX and GX and they were doing my head in. I still don't know how to do certain things I take for granted on my 50G, but things are considerably more spartan on the SX.

Using a slightly modified program (since I have TEVAL already built) my results for a real 48SX are:

n=1000
t=95.5s
Result=1395.3462877
