Timeline of Computer History
 

1961  
Components
RTL integrated circuit
Fairchild Camera and Instrument Corp. invented the resistor-transistor logic (RTL) product, a set/reset flip-flop and the first integrated circuit available as a monolithic chip.
Computers
IBM 1401
According to Datamation magazine, IBM had an 81.2-percent share of the computer market in 1961, the year in which it introduced the 1400 Series. The 1401 mainframe, the first in the series, replaced the vacuum tube with smaller, more reliable transistors and used a magnetic core memory.

Demand called for more than 12,000 of the 1401 computers, and the machine´s success made a strong case for using general-purpose computers rather than specialized systems.
Robots & Artificial Intelligence
UNIMATE
UNIMATE, the first industrial robot, began work at General Motors. Obeying step-by-step commands stored on a magnetic drum, the 4,000-pound arm sequenced and stacked hot pieces of die-cast metal.

The brainchild of Joe Engelberger and George Devol, UNIMATE originally automated the manufacture of TV picture tubes.
Storage
The IBM 1301 Disk Storage System
IBM 1301 Disk Storage Unit is released. The IBM 1301 Disk Drive was announced on June 2nd, 1961 for use with IBM’s 7000-series of mainframe computers. Maximum capacity was 28 million characters and the disks rotated at 1,800 R.P.M. The 1301 leased for $2,100 per month or could be purchased for $115,500. The drive had one read/write arm for each disk as well as flying heads, both of which are still used in today’s disk drives.
