Hello again,
First, I did the original test in a DOS box so don't know what else to do except
maybe try rebooting in dos mode. Sorry I only included one log file. Anyway
here is the test again with your >output.1 command. The PII is still about 38%
faster ?!
Here are the two log files (only the ends) for comparison. It's obvious that
the first one is the K6-2. Since I lose all screen info when running in the
>output.1 mode, I just let them both run about 100 seconds and then "end".
