Being the prowd owner of a 2620 board, I have been wondering just how fast is it compared to the othe 68020 boards. Has anyone done any comparsions of these boards(I do not trust ads as a general rule), by the way how did lattice get 5.02 to do over 1600 drystones a second anyways) that they would liketo share.

I have gotten the following using Lattice C 5.02 and Drystone benchmark Compiling lc -v -w -cf -L -O -m0 -rr drystone using Amiga 2000 /68000 w/ expansion RAM : Registers - 1923 drystones/sec No Regs - 1666 drystones/sec I did a changetaskpri 100 before I ran it and had to modify the linker file to also include lcs.lib since time() don't work with only lcsr.lib Using the same compilation but -m2 and the A2620 board enabled I get Registers - 5000 drystones/sec No regs - 4166 drystones/sec Some other benchmarks I got are (with A2620 enabled) fib 52 secs qsort 11 secs savage (25000) 4 secs 100 sieves 5 secs Whetstones - 769231 Whetstones/sec -Roger Uzun
