Perhaps vintage is a better term than
antique although, in Internet years, integrated circuits have been around for
more than 120 years. It is absolutely amazing the number and variety of computing
devices that have been created and obsolesced in just 40 years. Integrated
circuits are used for many purposes, but these pages focus primarily on vintage computing chips
from the 60's-80's.
Theses pages contain information on these vintage chips
that is difficult to find. Most publications are written for hardware and
software designers. Very few publications are suitable for collectors' needs. How
do you identify the chip? What do the markings mean? How can you tell which
company made the chip? When was it made? How was it made? What is the
history and significance behind the chip? These pages attempt to answer these
questions. There is information here for the beginning and the advanced
Here you will find
information about some of the most famous chips: Intel 4004, MOS 6502, and
Motorola 6800, some of the most innovative: RCA 1802 and Rockwell PPS-4, and
some of the more obscure: NEC uPD751 and National Semiconductor IMP-00A.
Microprocessors seem to be
the most common chips collected, so I have organized many of the pages around
them, but I have tried to include other items of interest such as the memory
chips, support chips, and other computing technologies.
