I would look at Phillips 80515 type devices, and see if you
happen to notice the pin outs are the same. ;-)  It is not
unusually to see copyright notices for Intel (8031 originator),
Phillips (80515 producer), and Bosch (who supplied the data for
the mask rom) on all the same package.

Cheers,

  The earliest units used the Cosmac 1802 

  Then came the 8051, 8052, and 80515 ....

  Next, they switched to 16bit uP's with variants of 
  the Intel 80x96

  Usually in combo with an SMD (44pin) 8051 for spark & knock control

  The latest OBD-II compliant M5.2 uses the 87C196KN

  PS: You can obtain a shareware package called DIS8051 from many sources
      on the net .... 

  PPS: If anyone has any 80x96 tools to share let me know!
