when did computers/chips first show up

What year did GM first put any form of computer or chip in a corvette, and what did it do?
Thanks

The first year of an ECM in a Corvette was the 1980 LG4 305. It had a computer feedback carburetor. The 305 had a oxygen sensor(in the exhuast), mixture control solenoid and a throttle positioning sensor(which were all part of the carburetor). They used the same system in the 1981 Corvettes and then in 1982 they went to a more sophisticated computer system when General Motors introduced the crossfire fuel injection system.

Would you consider the HEI ignition module a chip? If so I believe these came to the corvette in 1975 but don't hold me to that one

1975 is correct...but the HEI ignition module did not become part of the computer system until 1982.

would the earlier TI ignition be considered an early form of chip?

Well, sure, it's a chip of sorts, not ALL chips have to be 16 pin DIPS....

but yes, it has many control and power parts in it's construction....

years ago I met the guy who designed the updated HEI to .com with the 'mainframe'.....he is a Corvette man with a very well done highly modified C3....that is SO light it floats....
