1974 Intel P4040 4 bit CPU in new unused condition.
Antique microprocessor chip from 1974 era. A genuine 4 bit cpu made by Intel Corporation. Originally made for the calculator industry. Was the successor to the 4004 and then after the P4040 came the C8008 which was used in Altair and Cromemco, I suspect. If you have some old Tektronix or HP test gear, these may have been in them too.
