the chip itself
The expensive chip is soldered directly, eventually because at that time
there were no reliable 40-pin sockets available. But to remove it simply
for testing or repair, the small pcb on which it is located, has an extra
connector to the main board.
Details of the MK 6010
Interesting the japanese date which is stamped on the keramic body:
46.6.-6. The japanese counted years from the inauguration of their emperor.
Emperor Hirohito (1901* 1989+) was crowned in the year 1926. That means,
that the IC was stamped on may, 6th 1972, even it was fabricated in the
13th week of 1971. Also intersting the logo
