Digital Epuipment Corporation (DEC) made mincomputer from 1960 to about 1990. Microcomputers put DEC out of business with very good low cost computing. The first PDP computer was a PDP1 in 1960. Only about 3 of these computers still survive. The Computer History Museum in Mt. View, California has a restored PDP1 restored and in nice working condition.
Many versions of the PDP11 were made and about 600,000 were sold during its 20 year lifetime.
The core memory is nonvolatile and does not lose its memory when powered off for the day. This module has very tiny cores -probably 16k words of 16 bits each.
