This is the best post, with lots of data, that I've seen about this subject in a long time.
Bravo speed racer!
I have some questions:
What is the complete part number / mask for the 030 and 882 chips?
Are the CPU clocks, and or FPUclocks 60/40, or 50/50 duty cycle, if you know?
I saw your frequencies, but no manufacturers part numbers so I cant research this IMPORTANT difference in "clocks".
What type & qty of RAM(s) & its speed/part number?
I have never gone that fast on an 030, but I bet that machine feels pretty CRISP!!!
