Waow !
Very nice one !
What can be the use of such combination (slot1/80c51) ?

the chips range from 1989 thru to 1999 & the stickers late 99 & early 2000  with Coppermine being released Oct 1999
What is the part number on the Analog Devices chip 
being interesting to see if standard coppermine slot on the other side

This is interesting.
Tried on a board yet? |

AD595AQ 9904
the PCB is possible 9917
the youngest IC on this board is possible 9910 ( both the 87c51 and the max111BCWE) |

with a 1980 copyright on the 87C51... i would assume 8910 not 9910 
the AD595AQ is a Type K thermocouple amplifier (-55 → +125°C)
so looks like it was made to test the thermal design of intel computer cases or different HS & fan arrangements
the group of jumpers on the card possibly can be changed to simulate the thermal properties of different speed coppermines
the 87C51 would be used to process the data coming from the thermocouple via the amplifier chip, so the card can act as a self contained DAQ card. Unlikely it has a OS embedded on the card, but they probably had a boot disk for that.
Data then was probably either saved to the book disk (as the data file would be small) or sent via a serial cable to another computer.

| Yes, I thought some type of data logger for thermal testing... |

actually i dont know what it is.
Thank you for a great inference! |

Is it a terminator for multiple processor board ?

I dont think a terminator need a HS and fan attached.
and it need not to be such complicated circuit design.
This should be engineering probing tools for copermine cpu.
the "SC242 VTT rev4" might only means it's interface comply with that 242 pins slot connector's specifications or protocol.

Really cool !
SC242 = Slot1
Vtt (1.5V) is termination voltage...
But may be VTT is abbrev. of .....Testing or Verify....
definitely not a terminator
