What SpeedSys says:
Notice that RAM was reduced to 48Mb "only".
Above that amount the system gets unstable.
Tested thoroughly with many RAM sticks and L2 cache chips - no difference.
It is clearly POD L1 cache WB related, since the problem does not exist with 486 CPUs or POD + L1 in WT mode.

All scores are tiny bit lower than what was captured 1-2 years ago. Annoying, but don't ready to give up just yet.
Clearly remember the 18.8 number on screen and my "woah" reaction. Would like to experience it again.
Also, this was before the time when started capturing more details from the retro experiments - screenshots, videos, descriptions of what happened and how.
